In this section, we will consider the derivative function rather than just at a point. We also begin looking at some of the basic derivative rules.
Let f be any function. The derivative function of f is defined as: provided the limit exists Other notations:
Use the definition of derivative to find the derivative of the function.
Let n be any real number (not necessarily an integer). Then:
Find the derivative of each of the following functions. (a) (b) (c)
Let f be any differentiable function, let k be any constant, and let. Then:
Let f and g be any differentiable functions, and let. Then:
Find the derivative of each of the following polynomials. (a) (b) (c)
Give the equation of the tangent line to the curve at the point (1, 3).
