Answer:

$(cosb,s\imaginaryI nb)$

Step-by-step explanation:

In the unit circle ( a circle with a radius of 1) the coordinate (x, y) of a point on the circumference is given by the following expression:

where

$\theta\text{ is the angle formed between the point and the x-axis}$

In this case, that angle is b.

Therefore, The x-coordinate is given by

and the y-coordinate is given by:

The exact coordinates (x,y) of point P in terms of angle b are:

Answer:

$(cosb,s\imaginaryI nb)$
