The equality is valid for all values of x since tan–1x and cot–1x are Example 30 The greatest and least values of (sin–1x)2 + (cos–1x)2 are respectively.
sin -1 or arcsin is the inverse of the restricted sine function y = sin x
20 cos 30° + 4 sin 60° - 2 tan 60° can be written in the form ? where is an integer. Work out the size of angle y. Work out the area of the triangle
The six trigonometric functions can be used to find the ratio of the side lengths. The six functions are sine (sin) cosine (cos)
