I got pi/4. what did you get?

im not down to calculate anything atm sorry D:

would need an actual calculator or something more than the windows base calculator, which i dont have at hand

should give you the right answer though, are you being graded on this?

if you got pi/4, -pi/4 is also a good answer, so you have 2 answers
