The angles are provided in radians, as usual in the study of trigonometric functions: {eq}\frac{\pi}{6}, \frac{\pi}{4} {/eq} and {eq}\frac{\pi}{3} {/eq} in the first quadrant, and their equivalents in the other three quadrants - {eq}\frac{2\pi}{3}, \frac{3\pi}{4}...

Inverse FunctionsCopyright © 1997–2024 by Stan Brown, BrownMath.comSummary: The inverse trig functions (also called arcfunctions) are similar to any other inverse functions: they go from the function value back to the angle (or number). Their ranges are restricted, by definition, because ...
For, if y = arcsec x, then the angle y falls either in the first or second quadrants. When angle y falls in the first quadrant, then both sec y and tan y are positive. Therefore their product is positive.When angle y falls in the second quadrant, sec y and tan y are both ...
(2) = 1, which is the correct value for the tangent. The values of the sine and cosine for a45°angle are the same;sin(θ) = sqrt(2)/2andcos(θ) = sqrt(2)/2. If you need to find one of the co-functions (such as cosecant), you may be required torationalize some ...
We can rotate the radial line through the four quadrants and obtain the values of the trig functions from 0 to 360 degrees, as in the diagram below: For example, for an angle that leads to the second quadrant (90-180°), the cosine will be negative as the horizontal projection of the...
as usual in the study of trigonometric functions: π6,π4 and π3 in the first quadrant, and their equivalents in the other three quadrants - 2π3,3π4,5π6,7π6,5π4,4π3,5π3,7π4,11π6 - as well as the angles that lie in the coordinate axes - 0,π2,π,3π2 and ...
