Is there a point in learning trig?

Knowing trig makes learning calculus easier.

In the US, Trig is normally considered as a high school level course, however, it is not a required course to graduate. I believe Algebra is the highest of the high school math courses that are required for graduation, although some schools may still only require Geometry.\nIn the US the typical sequence for math courses is Pre-Algebra, Geometry, Algebra, Trigonometry and then Calculus (which is usually taken at the high school level as Pre-Calculus, but may also be taken as full "AP" Calculus, where the "AP" stands for "Advanced Placement" and means that the student can get University-level credit for that course when they go to College).

I forgot how to do those, but it's some sort of trig identity isn't it?  Like\n\nsqrt (1-tan [x])\n\nProbably not though.

Not really, you should really talk to your math teachers about it. It leaves no room to get a real answer for in class questions and showing the step by step process for problems.

surveying does use it alot and so does desgining and architecture. Engineering, construction and factories and industries all use it. There are many jobs out there were trig can help. I hated it but it shocked me how much I have used it now.

Algebra is needed for SO many things! Recipes, budgeting you name it. It teaches problem solving. Geometry is good to shape your mind to think logically. I actually took geometry twice out of my own free will because I loved proving the angles were equal or whatever. My mind was never so sharp. Trig, well I actually haven't found a use for that yet....

I would be very surprised if you could do that. Algebra I, algebra II, geometry, and trigonometry classes are available separately because they are very different from each other. They also get harder as you go up to the next level.

You're supposed to print a table, right? The question is poorly written, so it's not clear, but I'll assume that's the goal.\n\nWell, it sounds like you can write your loop, so shouldn't you just print out the sine, cosine, and tangent of the angle in the body of the loop?  It's not clear what the stumbling block is.  You realize that there are built in functions that compute sine, cosine, etc.?

Yes. Think of the trignometric circle (radius = 1 and centered at the orgin (x=0, y=0). The so called tangent, is the line x=1 (that *is* tangent to this circle). The numeric value that we call tangent of an angle (alfa) is the y value of the intercept of a line passing thru the origin and forming an angle = alfa with the x-axis.\nIn other words, draw a trignometric circle and a verticle line tangent given by x=1. Draw another line forming an angle w/ the horizontal axis and passing thru the origin an stretch it so that it crosses that line. The height of the point of intercept of these two lines is the value of the tangent.\n \nThe co-tangent is the same but w/ y=1.\n \nEdit:\nThe secant is the distance from the origin to the intercept in the explanation above. Since it is a segment of the diameter, it is over a line that separates the trig circle, and is thus a secant.\n\nCheck out this link (skip the beginning of the page):\nhttp://www.npcts.edu/math/PreCalculus/Transcendental/Trigonometric/Definition/index.html

There is only 2 ways to know an angle\n1. Know the other two angles \n2. know the length of 2 sides\nSince you don't know the other two angles, you need to use one of your trig functions, the only way to do this is to memorize the tables for sin, cos and tan for as many angles as you can manage, and then use your memorized chart once you figure out what ratio you are using.

Take a unit circle and a point p on the circle. Embed the circle to be centered at the origin on a Cartesian xy-plane. The cosine of p, cos(p), is the x-coordinate, or abscissa, of p. The sine of p is the y-coordinate. These functions are the projection functions for the unit circle. \nIt is common to give the points p on the 1-dimensional circle the coordinate referring to the arclength between p and the positive x-axis (as measured clockwise). Thus, the point (1, 0) on the unit circle is given the native coordinate (0), or 0 for short. Inversely, the point 0 in the unit circle has Cartesian coordinates (cos(0), sin(0)). Since the circumference of a circle is 2Pi, a point that is a quarter of the way around the circle from the positive x-axis is given the coordinate 2Pi/4 = Pi/2 and so forth. This system of coordinates is called radians and is the native way of measuring angles, as each angle has a unique radian measure. \nThis relationship can be seen by drawing a radius from the origin to mark the angle and assigning it the radian measure of wherever it intersects the unit circle. There are more analytical reasons as well, as you go on to study calculus.\nThe radius drawn above also gives the relationship between these circular projection functions, and the way one first encounters trigonometric functions, as ratios of the sides of right triangles. Now you should be able to visualize the triangles inside the unit circle (or any larger circle, dependent on the triangle's hypotenuse), and see why the trigonometric functions are cyclic in 2Pi, and derive some properties of the trigonometric functions that are not easily apparent from just looking at right triangles.\nThe tangent function is so named because it is the length of a certain tangent to the circle; a tangent drawn from the positive x-axis to where it meets an extended radius of the circle. You may be able to work out the equation tan(p) = sin(p)/cos(p) from the geometry involved. If you're familiar with the secant function, (1/cos(p)), you may want to know that it is a geometric secant as well. See the sources below for pictures.

im taking Trig. try finding a homework helper web page. or go to the book that ur learning from web page because the majority of the times they have practice help on there.

I'll give you a hint and let you try to figure out the rest yourself (unless someone else tells you the exact answer). =)\n\nUse your trig identities:\n\ntan A = sinA/cosA\n\ncot A = 1/tanA or cot A = cosA/sinA

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.

trigonometry is the study of angles in one or several triangles. it is a little like geometry, in the sense that it deals with shapes, but it also has characteristics similar to algebra and basic number functions. it's not too difficult once you learn how to work a scientific calculator.

Trigonometry is basically about the relationships between angles and their corresponding ratios in distances.\n\nTrigonometry has many applications such as:\n\n- Navigation (Sextant)\n- Land surveying\n- Building\n\nIt is also used extensively in a number of academic fields, primarily:\n\n- Mathematics\n- Science\n- Engineering\n\nFor non-mathematicians and non-scientists applications, trigonometry is used in:\n\n- Measurement problems\n- Theory of music\n- Number theory\n- Fourier series\n- Fourier transforms\n- Statistics

SAT II 1C covers basically up to that point, knowing some trigonometry ooncepts wouldnt hurt. But if you mastered precalc then that means that your geometry and alg 2 skills should be alright.  Although, if you want a good score on the 1C test, its much harder, since many students that take the test do very well, getting a good score will be hard if you are at this disadvantage of not knowing more. If you have time, go for the other test, the one after it...
