Final answer:
To find the derivative of the function y = r r² 1, we can use the power rule of differentiation which states that the derivative of a function of the form f(x) = x^n is f'(x) = nx^(n-1). In this case, the derivative of y = r r² is y' = 2rr'.
Step-by-step explanation:
To find the derivative of the function y = r r² 1, we can use the power rule of differentiation. The power rule states that if we have a function of the form f(x) = x^n, then its derivative is given by f'(x) = nx^(n-1). In this case, since we have a constant term of 1, we can ignore it when taking the derivative. So, the derivative of y = r r² is y' = 2rr', where r' represents the derivative of r with respect to x.
