Question

I will fan and medal!
Write the following expression as a function of a positive acute angle. Use "+" to indicate a positive value and "-" to indicate a negative value.

sin312°

Answer 1

Fact 1. An angle of 312 is the same as an angle of 312-360
Fact 2. sin(-theta) = -sin(theta)

360-312= 48
its in the IV quadrant so we know the sin is negative
so its - in your first blank and 48 in your second.

sin312 = -sin48
