Calculating Derivatives and Inverse Functions

The video tutorial explains how to find the derivative of a function using the product rule. It involves differentiating the function f(x) = 2x^7 * inverse hyperbolic sine of 5x. The process includes applying the product rule, differentiating the inverse hyperbolic sine function, and simplifying the expression. The tutorial also demonstrates how to calculate f prime of 1 by substituting x=1 and evaluates the result using calculators like the T84 and Desmos. The video concludes with a summary of the steps and results.
