Question

I just need this answered as fast as you can please

Answer 1

`(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

`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)`
