Question

If sin theta = (square root 3)/2, then theta=60 degrees.
True or False?

Answer 1

 Let @ = theta. 

sin @ = sqrt(3) / 2 

The sine function equals sqrt(3) / 2 at the following angles measured in degrees: 
....,-300, 60, 420, 780,1140,....,60 + 360k and 
....,-240, 120, 480, 840, 1200,....,120 + 360k where k is an integer. 

@ = 60 + 360K and 
@ = 120 + 360K 

if k =  0 ; @ = 60 degrees ;

ANSWER: 

True
