Webb9 maj 2016 · Explanation: Let's draw a right triangle with an angle of a = cos−1(x). As we know cos(a) = x = x 1 we can label the adjacent leg as x and the hypotenuse as 1. The Pythagorean theorem then allows us to solve for the second leg as √1 −x2. With this, we can now find sin(cos−1(x)) as the quotient of the opposite leg and the hypotenuse. sin ...

WebbHow would i do this with sin ( 2 arccos ( x)) or tan ( arccos ( x) + arcsin ( x))? Edit: From the answer given, i will try to solve these two equations. sin ( 2 arccos ( x)) = 2 sin ( arccos ( x)) cos ( arccos ( x)) sin ( arccos ( x)) sin ( θ), θ = arccos ( x) cos ( θ) = x A = θ, hypotenuse = 1, adjacent = x, opposite = 1 − x 2 sin ( θ) = 1 − x 2 WebbWe did not get what we want. There is a function to perform this simplification, called factor(), which will be discussed below.. Another pitfall to simplify() is that it can be unnecessarily slow, since it tries many kinds of simplifications before picking the best one. If you already know exactly what kind of simplification you are after, it is better to apply … WebbYou will need to use the idea you used, plus some trigonometric identities. For the first, you will need sin 2 θ = 2 sin θ cos θ. For the second, you will sort of (but not really) need tan ( … litho printers in edinburgh
