NettetIntegral of cos^2 (2x) Recall the double angle formula: cos (2x) = cos^2 (x) – sin^2 (x). We also know the trig identity sin^2 (x) + cos^2 (x) = 1, so combining these we get the equation cos (2x) = 2cos^2 (x) -1. Now we … NettetDerivatives Derivative Applications Limits Integrals Integral Applications Integral Approximation Series ODE Multivariable Calculus Laplace Transform Taylor/Maclaurin …
