In order to find the values of trigonometrical functions for any angle in terms of those of positive acute angle, we have the following algorithm (from my textbook):ALGORITHMSTEP I: See whether the given angle a is positive or negative if it is negative, make it positive ...
How to find sin(x) given sec(x)? Prove the identity. cos(x + pi/2) = -sin x. Prove that the equation is an identity. (cos 2x)/sin^2x = csc^2 x - 2 Prove that \sin(x + \pi) = -\sin x How do you prove (1 - tan(x))^2 = sec^2(x) - 2tan(x)? Prove identit...
Find the cosecant of the product for both triangles, this number will be the length of the dividing line that forms the hypotenuse. The cosecant is often found on calculators as either "csc", "asin", or "sin^-1". For example the cosecant of 0.15 would be 8.63 (csc15 = 8.63). St...
