Good evening all!
Just started my online Precalc-Trig class and I am already confused............lol good sign. Anyway...
Using the conversion factor π rad = 180° for A i get 0.524 rad. But as you can see the book gives an answer of π/6 rad. How in the hell do they get that? All's I did was the math in the conversion...30° * π rad / 180°...got that decimal. I noticed that 180/30 = 6 but so what? Why would I do that...and in "C" 180/-135 certainly isnt 3/4.
What gives
