$\int e\cos\left(x22\pi +\pi \right)\pi^{2}^xdx$
Learn how to solve integral calculus problems step by step online. Find the integral int(pi^2^xecos(x22pi+pi))dx. Calculate the power \pi ^2. The integral of a function times a constant (e) is equal to the constant times the integral of the function. The integral of a function times a constant (\cos\left(x22\pi +\pi \right)) is equal to the constant times the integral of the function. The integral of the exponential function is given by the following formula \displaystyle \int a^xdx=\frac{a^x}{\ln(a)}, where a > 0 and a \neq 1.
