$ \sin^2 \theta Half- angle for cotangent, $ \cot \frac{\theta}{2} = \frac{1 + \cos \theta}{\sin \theta} $. 1 Mar 2018 Half Angle Formula - Sine. We start with the formula for the cosine of a double angle that we met in the last section. cos 2θ = 1− 2sin2 θ where the sign depends on the quadrant of θ. Dividing this identity by either sin2 θ or cos2 θ yields the other two Pythagorean identities:. The trigonometric ratios of an angle in a right triangle define the relationship between the angle and the length of its sides.
