Indefinite Integral • The family of antiderivatives of a function f indicated by • The symbol is a stylized S to indicate summation
Indefinite Integral • The indefinite integral is a family of functions • The + C represents an arbitrary constant • The constant of integration
Properties of Indefinite Integrals • The power rule • The integral of a sum (difference) is the sum (difference) of the integrals
Properties of Indefinite Integrals • The derivative of the indefinite integral is the original function • A constant can be factored out of the integral
Example : Find the function f such that • First find f (x) by integrating.
Examples • Determine the indefinite integrals as specified below
Given that the graph of f(x) passes through the point (1,6) and that the slope of its tangent line at (x.f(x) is 2x+1, find f(6)
