Find The Terminal Point On The Unit Circle Determined By Π2 RadiansUse Exact Values Not Decimal Approximations class=

Sagot :

Okay, here we have this:

Considering the provided information, we are going to determine the requested terminal point, so we obtain the following:

So for this we will first calculate how much the given angle is in degrees, from there then we proceed to observe in the unit circle, then we have:

(pi/2)*(180°/pi)=180°/2=90°

We can observe in the image of the unit circle that the terminal point of 90° is (0, 1).

Finally we obtain that the terminal point of pi/2 radians is (x,y)=(0, 1).
