sin arctan x sqrt 1 x 2 Consider the right angled triangle with sides 1 x sqrt 1 x 2 Let phi be the angle opposite to the side of length x We find that phi arcsin x sqrt 1 x 2
We want an angle call it A of this triangle to be arcsin x For that to happen the triangle might have hypotenuse c 1 and side opposite the Compute arcsin x arctan Sin arctan x x sqrt x 2 1 The solution arctan x is an angle whose tangent function x 1 Considering the sides of the right triangle We have opposite side
