Enter the angle you wish to convert and this power reducing calculator will determine the **sin ^{2}θ** ,

**cos**, or

^{2}θ**tan**of that angle.

^{2}θ## Power Reduction Formula

The following formulas are used to calculate the power reduction of an angle in trigonometric terms.

sin^{2}θ = [1 – cos(2θ) ] / 2

cos^{2}θ = [1 + cos(2θ) ] / 2

tan^{2}θ = [1 – cos(2θ) ] / [1 + cos(2θ) ]

## Power Reducing Definition

Power reducing is the process of calculating the squared value of the three trigonometric functions using a reducing power function as shown above.
