The video tutorial explains how to determine the derivative of a function using logarithmic differentiation. It covers the steps to isolate the function, apply logarithmic properties, and differentiate using chain and product rules. The tutorial also demonstrates how to calculate the derivative at a specific point using a calculator, ensuring the calculator is in radian mode. The process is verified using the numerical derivative function on a TI-84 calculator, highlighting the importance of understanding the derivative's role in determining the slope of a tangent line.
