Question

Find the exact value in radians.






Super bad at radians so an explanation would be nice as well since I have quite a few of these problems!The test is tomorrow!!! Also no calculator is allowed.

Answer 1

I'm also on my phone so I apologize for any delay of reply.

Answer 2

A radian is a unit of measure for angles which usually corresponds to the arc length of the angle measured

Answer 3

\[1 radian= \frac{ 180 degrees }{ \pi } \approx 57.2958 degrees\]

Answer 4

I've dealt with radians in class it's just that I'm terrible at them and I dont remember how to solve for them with these particular type of problems

Answer 5

This conversion factor can help you solve for radians and degrees and back\[degrees = radians \times \frac{ 180 degrees }{ \pi }\]
\[radians = degrees \times \frac{ \pi }{ 180 degrees }\]

Answer 6

Okay. I've tried that before, maybe I'm just doing my mental math wrong. So is it ok for me to solve in degrees then just convert?
