Power Reducing Formula (Trigonometry) Power-reducing formulas convert higher powers of trig functions to first power (for integration). — free online calculator.

Formula

sin²(θ) = (1 - cos(2θ))/2; cos²(θ) = (1 + cos(2θ))/2
  • Power Reducing Calculator calculates its result from Angle θ. It uses the formula sin²(θ) = (1 - cos(2θ))/2; cos²(θ) = (1 + cos(2θ))/2. Change any input to recalculate the result instantly.
  • The main inputs are Function, θ. Enter them in the units and format shown in the calculator.
  • Keep comparable quantities in compatible units whenever the formula combines or compares them.
  • Changing any input above recalculates the result with the same calculation engine used by this page.

Example: Power Reducing

Inputs
  • Function: sin2
  • θ: 30 degrees
