What angles have an exact expression for their sines, cosines and tangents? You might know that cos(60°)=1/2 and sin(60°)=√3/2 as well as tan(45°)=1, but are 30, 45 and 60 the only angles up to 90° with a formula for their trig values? No! There are lots more but not all angles have exact expressions involving nothing more than square-roots.

Substitute values of sine and cosine functions According to the trigonometry, the exact values of sin 30 degrees, sin 45 degrees, cos 30 degrees and cos 45 degrees are already known to us. (1). sin (45 ∘) = 1 2
