The video introduces the power rule for derivatives, explaining that for a function of the form $y = ax^n$, the derivative $\frac{dy}{dx}$ is found by multiplying the coefficient ($a$) by the exponent ($n$) and then reducing the exponent by one ($anx^{n-1}$) [-]. Applying this to the first example, $y = 2x^3 + 4$, the derivative is calculated by multiplying 3 by 2 and subtracting 1 from the power of $x$, resulting in $6x^2$, while the derivative of the constant term, 4, is 0 [-].
