Enter the angle you wish to convert and this power reducing calculator will determine the sin2θ , cos2θ , or tan2θ of that angle.
Power Reduction Formula
The following formulas are used to calculate the power reduction of an angle in trigonometric terms.
sin2θ = [1 – cos(2θ) ] / 2
cos2θ = [1 + cos(2θ) ] / 2
tan2θ = [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.
