Question

I just need this answered as fast as you can please

Answer 1

Answer:

$(cosb,s\imaginaryI nb)$

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

$cosb$

and the y-coordinate is given by:

$sinb$

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

$(cosb,sinb)$

Answer:

$(cosb,s\imaginaryI nb)$
