What role does trigonometry play in medical professions?

there are lots of medical devices taking ideas from trigonometry.\none simple example is hip prostheses..the angle at which it should be designed implanted and all are decided by trignometric techniques. I can give you more examples if you r really interested

Rectangular coordinates are component of the vector where the polar form gives all the information in a compact form. It helps to see the magnitude (how much) and phase (which way) versus having it seen as part of it is in this direction and the other part is the other. Sinusoidal and harmonic expression representation is easily described in the euler's identity/mathematics which translates to better visual representation in polar of the theory on hand.

Math is needed for lots of things!\nDo your homework!\n\nhttp://mathforum.org/dr.math/faq/faq.why.math.html\nThere are actually thousands of different jobs that require some knowledge of mathematics. Here are more than 30 firsthand accounts from Mathematicians at Work telling what some college math majors are doing, from an Air Traffic Control Systems Analyst and a Lawyer to a Data Capture Facility Troubleshooter on the Hubble space telescope.\n\nExactly How Is Math Used In Technology?, from the Mathematics Department of the British Columbia Institute of Technology, provides examples of math uses for biomedical engineering, food technology, building technology, chemical sciences, civil and structural engineering, graphics and computer-aided drawing (CAD), electronics, environmental health, mechanical engineering, mining technology, nuclear medicine, occupational health, petroleum technology, prosthetics, forestry and wildlife, robotics, and surveying.

I'm not sure if I get your question right, but I think you're referring to lookup tables (or LUTs).  I think the easiest way to explain the use of these, is through an example from the old days.  Twenty years ago (or so), it took a long time to calculate the sine of an angle.  So if you needed to make a lot of calculations with sines in them, what you did was: calculate the sines of each of the 360 degrees (or more if you needed a better precision) and store the results in an array.  If you then needed the sine of n, all you needed to do is look up the value of the n'th entry in the array --which was a lot faster and therefore efficient than calculating the value.\n\nOf course, this only helped if you needed to calculate a sine more than 360 times, otherwise you wouldn't win back the overhead of pre-calculating all those sines.\n\nHTH.\n\nPS: a conclusion of what I wrote should be that using arrays with[in] loops does NOT *always* improve efficiency.

If you are thinking about becoming a doctor you need to know that it is a tough road but if you make it to the end it can be a rewarding career.  Now as far as telling you about doctors and their tools it depends on what type of doctor you are talking about because there are all kinds of doctors and tons of different tools that they use.  So to sum it all up I don't want to give you the best answer I want to give you an accurate one.  And this would be it.  Doctors have a spectrum of fields that they are into and they all have unique instruments such as a OB/GYN doctor uses speculum's to do pelvic exams.  A neurologist uses an EKG machine to measure electronic waves in the body.  A cardiologist use a scalpel to cut into the heart and sometimes uses laser surgery to remove plaque from the heart.  I hope I have helped you.

I hope I get this right, it has been a very long time since I took geometry and I was not very good at it. But here goes. Geometry is the mathematical study of lines, angles, circles, circumferences,triangles and the formulas needed to deduce these ordinary objects correct degree of angle or the volume contained within the circumference of an object. I think I may have left something out, but right now that is all I remember.

Cosine, one of the six fundamental ratios of trigonometry. In any right triangle, the cosine of an acute angleA, usually written cos A, is defined as the ratio of the length of the side (that is not the hypotenuse) of the triangle that is adjacent to the angle, divided by the length of the hypotenuse of the triangle.

Personally I would take Trig when I had time to devote to it. I took College Algebra, Chemistry, and Trig all at once and I have to tell you, trig never made any sense to me.

Trigonometric functions also work for a variety of harmonic functions--the speed of a swinging pendulum, the displacement of a bobbing spring, the currect in an inductor in a LCR circuit, etc.  Sin(e) and cos(ine) describe waveforms that are called sinusoidal functions.  Tan(gent) involves the sin/cosine ratio.

The word "Trigonometry" is derived from two Greek words meaning measurement or solution of triangles. Trigonometry is a branch of mathematics that deals with the ratio between the sides of a right triangle and its angles. Trigonometry is used in surveying to determine heights and distances, in navigation to determine location and distances, and in fields like nondestructive testing for determining things such as the angle for reflection or refraction of an ultrasound wave.\n\nThere are three principle functions in trigonometry: sine A, cosine A, and tangent A where A is an angle. These are typically abbreviated for use in algebra to: sinA, cosA, and tanA. These terms are defined in terms of a right triangle. SinA is equal to the side opposite of the angle A (side a) divided by the hypotenuse of the triangle (side c). From the right triangle below, it can be seen that the value of angle A is directly linked to the ratio of side a and side c. In other words, if the length of side a is changed (and side c is not changed by the same amount), then angle A must change. When the division of the length of side a by side c is performed, the resulting value is directly related to angle A. The relationship between the decimal value of the ratio of the side and the angular value of angle A can be looked up in trigonometry tables or, as is more common these days, programmed into a scientific calculator. The relationship between angle A and the ratio of any two of the three sides can be determined by using either the Sin, Cos or Tan functions. CosA is equal to the side adjacent to the angle A divided by the hypotenuse and tanA is the sine divided by the cosine and is therefore the side opposite the angle divided by the side adjacent.

The trigonometric identities have as their primary purpose to simplify calculations.  For example, why evaluate 2sinxcosx when you can evaluate sin2x.\n\nAs for the applications, oblique triangles are used in surveying and mapping.  For example, suppose you want to know your distance from an object on the opposite side of a river.  You can mark off a line of a fixed distance, say 100ft.  Then, go to the opposite ends of the line and use a transit to measure the angle between the object and the line you measured.  You can now determine all three sides with this information.

The cosine laws apply to triangles which are NOT right angled. I think you have maybe read that wrong:\n\nhttp://www.themathpage.com/aTrig/law-of-sines.htm\n\ngives you a full guide to using the cosine laws to solve problems like these.

First is the spelling.  It's trigonometry.\n\nSecond is the question.  You would need to be more specific.  There are many good online sources for that.  Just google it and search the sites.  There will be some university level sites or some simpler ones too.

Try subjects that include Applied Trigonometry. My experience was in tool and die repair. Search metalworking topics, and other subject matter that actually USES trigonometry. This way it will be MUCH easier to relate to how and why trigonometry is useful.

I think they have to do with machines that support lives or save lives. It is not that easy of a major because you have to be a doctor (know about health, body, humans etc you know all the biology stuff) and also know about engineering (how to build a machine, mathematics, logic) so that you build a machine that solves a certain health problem or a machine that supports a sick person. For example, a biomechanical engineer would build a machine that pumps blood through a human's body, so that humans with heart problems can be supported. I think all the machines you see in hospitals are build by biomechanical engineers.
