Question

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

Answer 1

sin 60 degree = sqrt(3)/2

Answer 2

Can you explain how you got to that?

Answer 3

Idk what to do though

Answer 4

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

Answer 5

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

Answer 6

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
