Tangent Penta Angle Identity Calculator: Simplify tan(5θ)

Calculate tan(5θ) with the Penta Angle Identity

Enter the angle θ for which you want to calculate tan(5θ).

Discover the power of the Tangent Penta Angle Identity with our intuitive online calculator. Easily compute tan(5θ) for any given angle θ, leveraging the complex trigonometric identity to simplify calculations. Perfect for students and professionals in mathematics and engineering.

Formula:

The Tangent Penta Angle Identity expresses tan(5θ) in terms of tan(θ). The formula used by this calculator is:

tan(5θ) = (5 tan(θ) - 10 tan3(θ) + tan5(θ)) / (1 - 10 tan2(θ) + 5 tan4(θ))

Where:

  • θ (theta) is the input angle in degrees or radians.
  • tan(θ) is the tangent of the input angle.

This identity allows you to expand and evaluate the tangent of five times an angle without needing to first multiply the angle by five.
