Question

Write the following expression as the sine, cosine, or tangent of a double-angle. Then find the exact value of the expression. 2 tan π / (1 - tan^2 π)

SnapAndSolve AI · Accepted Answer

The expression 2 tan π / (1 - tan^2 π) is the formula for tan(2θ), where θ = π.Since tan(π) = 0, we have: 2 tan π = 2 * 0 = 0 tan^2 π = 0^2 = 0 1 - tan^2 π = 1 - 0 = 1 Therefore, the expression simplifies to:0 / 1 = 0The exact value of the expression is 0.
