Evaluate sin 60° without using a calculator by using ratios in a reference triangle.

Question

anonymous · Answer

sin 60 degree = sqrt(3)/2

anonymous · Answer

Can you explain how you got to that?

anonymous · Answer

Idk what to do though

anonymous · Answer

the trig function sin is always positive on first and second quadrant 
look at the circle below

anonymous · Answer

on the second quadrant 60 degree is (-1/2, sqrt(3)/2), so since sin is positive on the second quadrant, we take the point sqrt(3)/2

anonymous · Answer

remember the faze All Student Take Courses. 
All means all of the trig functions are positive on the 1st  quadrant
Student = sin is positive on the 2nd quadrant
Take = tan is positive on the third quadrant 
Courses = cos is positive on the 4th quadrant
