... You will need to be able to find the trig functions of quadrantal angles and of angles measuring 30°, 45° or 60° without using a calculator. Since sin θ = y and cos θ = x , each ordered pair on the unit circle corresponds to (cos θ , sin θ ) of some angle θ. We’ll show the values for sine and cosine ...
