Best ResponseYou've already chosen the best response.1you wanna use either a tan(a+b) or a tan(ab) formula than; and find 2 angles that either add to or subtract to 5pi/8

Best ResponseYou've already chosen the best response.1it is 225 degrees/2 tho; so maybe split that tan into sin and cos functions and work on half angle formulas

Best ResponseYou've already chosen the best response.1well; i think it finally settles down to: 1  sqrt(2)
