The value of is

We need to find the value of:

Let us simplify the trigonometric function.

We can write as:

Similarly,

Since, lies on IV Quadrant and cosine is positive in IV Quadrant.

And since, lies on IV Quadrant and sine is negative in IV Quadrant.

Using property of inverse trigonometry,

sin^-1(sin A) = A and cos^-1(cos A) = A

=0
