The tangent line is horizontal when the slope is zero.

Two tangents can be drawn to a circle from a point outside the circle. No tangent line can be drawn through a point within a circle, since any such line must be a secant line.

The graph of y = x2. When dy dx = 0, the slope of the tangent to the curve is zero and thus horizontal. The curve is said to have a stationary point at a point where dy dx = 0.

In geometry, a horizontal line is one which runs from left to right across the page. It comes from the word 'horizon', in the sense that horizontal lines are parallel to the horizon. ... A vertical line is perpendicular to a horizontal line. (See perpendicular lines).

So, in your case, W(sinx,cosx)=sinx⋅(−sinx)−cosx⋅cosx=−sin2x−cos2x=−1≠0 for any I, so sinx and cosx are linearly independent on any interval I.

Hyperbolic Functions: Inverses. The hyperbolic sine function, sinhx, is one-to-one, and therefore has a well-defined inverse, sinh−1x, shown in blue in the figure. In order to invert the hyperbolic cosine function, however, we need (as with square root) to restrict its domain.

Horizontal Lines A horizontal line is a line whose equation is of the form =, where is a real number. All points that lie on the line have a -coordinate of . The slope of any horizontal line is zero, 0. Example: Graph the line =2 and find its slope.

All horizontal lines have slope of 0. If lines are parallel then they have the same slope. The slope of a line parallel to the x -axis is 0.

sinx is known as a periodic function that oscillates at regular intervals. It crosses the x-axis (i.e. it is 0 ) at x=0,π, and 2π in the domain [0,2π] , and continues to cross the x-axis at every integer multiple of π .

Inverse Sine Function (Arcsine) Each of the trigonometric functions sine, cosine, tangent, secant, cosecant and cotangent has an inverse (with a restricted domain). ... The inverse of sine is denoted as Arcsine or on a calculator it will appear as asin or sin-1.

more ... The horizontal value in a pair of coordinates: how far along the point is. The X Coordinate is always written first in an ordered pair of coordinates (x,y), such as (12,5). In this example, the value "12" is the X Coordinate. Also called "Abscissa"

In your case, the function cot(x) is defined as 1tan(x) , which is cos(x)sin(x) . So, the zeros of the denominator are the ones of the sine function which, periodicity apart, are 0 and π . So, your vertical asymptotes are vertical lines of equations x=0 and x=π .

= 0.500. The sine function, along with cosine and tangent, is one of the three most common trigonometric functions. In any right triangle, the sine of an angle x is the length of the opposite side (O) divided by the length of the hypotenuse (H). In a formula, it is written as 'sin' without the 'e':

The x-axis is horizontal, and the y-axis is vertical. One way to remember which axis is which is 'x is a cross so the -axis is across'.
