Learn how to solve integral calculus problems step by step online. Integrate int(3x+(27x)/(x^2-9))dx. Simplify the expression inside the integral. Rewrite the fraction \frac{x}{x^2-9} inside the integral as the product of two functions: x\frac{1}{x^2-9}. We can solve the integral \int x\frac{1}{x^2-9}dx by applying integration by parts method to calculate the integral of the product of two functions, using the following formula. First, identify u and calculate du.
Solving a math problem using different methods is important because it enhances understanding, encourages critical thinking, allows for multiple solutions, and develops problem-solving strategies. Read more
Integration assigns numbers to functions in a way that can describe displacement, area, volume, and other concepts that arise by combining infinitesimal data.
