Question

Find the requested function value meeting all of the given conditions ...... sinO=√3/2 and tan>0 find cos0

Answer 1

use the phethgorian therom to show that sin x= opposite/hypotenuse ( the angle in the first first quadrant from the given conditions) ===> 3+m^2 = 4===> m=1 ( taking only the positive solution)===>cos x = 1/2
