Question

Given cos 0 = 3\4 and angle 0 is in Quadrant IV, what is the exact value of sin 0 in
simplest form? Simplify all radicals if needed.

Answer 1

-sqrt7/4 would be the correct answer with radicals. if you set up the given information for your right triangle in quadrant 4, the right side or the other leg of the triangle would need to be negative, therefore your answer will have a negative sign in front of the sin of theta
