$\int\frac{\ln\left(tx\right)}{e^{2}}dx$

Learn how to solve calculus problems step by step online. Calculate the integral of int(((ln(t*x)/(2.718281828459045^2)))dx. Calculate the power e^2. Take the constant out of the integral. Solve the integral \int\ln\left(tx\right)dx applying u-substitution. Let u and du be. Isolate dx in the previous equation.

$\frac{\frac{18}{133}tx\ln\left(tx\right)-\frac{18}{133}tx}{t}+C_0$
