The Derivative at a Point (Calculus Problems and Solutions)
390 views on YouTube
Use the limit definition of the derivative to find the derivative f(x)=x^2 at x=2, f(x)=1/x^2=x^-2 at x=-1, and f(x)=sqrt(x)=x^1/2 (square root) at x = 4 (use a difference quotient in each case). Interpret the derivative as the slope of a tangent line and rate of change. Use linear approximation to estimate a function value.
