Understanding Taylor Polynomials and Derivatives

The video tutorial explains how to find the coefficient of the term containing (x + 2)^4 in a Taylor polynomial centered at x = -2. It begins with an introduction to the problem, followed by forming the Taylor polynomial. The tutorial then details the calculation of the first to fourth derivatives of the function. Finally, it evaluates the fourth derivative at x = -2 and divides by 4 factorial to find the coefficient, which simplifies to 60.
