$\int e^{121x}dx$
Learn how to solve problems step by step online. Find the integral int(1/(e^(-121x)))dx. Since the exponent of the denominator is negative, we can bring it to the numerator and thus simplify. We can solve the integral \int e^{121x}dx by applying integration by substitution method (also called U-Substitution). First, we must identify a section within the integral with a new variable (let's call it u), which when substituted makes the integral easier. We see that 121x it's a good candidate for substitution. Let's define a variable u and assign it to the choosen part. Now, in order to rewrite dx in terms of du, we need to find the derivative of u. We need to calculate du, we can do that by deriving the equation above. Isolate dx in the previous equation.
