Best ResponseYou've already chosen the best response.1Why? The technique of letting pi = 180 is not very popular.

Best ResponseYou've already chosen the best response.1oh because in my class we had to draw out a circle with different measuements and memorize it, and i completely forgot that i was supposed to use the circle to solve it

Best ResponseYou've already chosen the best response.1I mean I would solve it algebraically as you have using the substitution of pi with 180, but the thing is, now that you know what the exact value is, you can still do it the way your teacher wants.

Best ResponseYou've already chosen the best response.1There's another technique that amistre 64 knows that's a huge shortcut for memorizing the unit circle that I know you would like. Ask him about it.
