Preview • Introduce antiderivatives/ indefinite integral • Introduce integration formulas • Initial Value Problems • Word Problems
Reverse Operation of Differentiation is the derivative of is an antiderivative of
Example 1 is the derivative of is an antiderivative of
Example 1 is the derivative of functions of the form
Example 1 The antiderivative of is of the form
Notation Differential Integral Sign
Notation Integrand Constant of Integration/ Arbitrary Constant
Notation The notation always comes in pair.
Notation If the independent variable is in u, then the differential is du
Formula where k is a constant Why?
Formula Verify
Formula where k is a constant
Example 3 Tradition
Remark on the integral notation Use parenthesis if there are two or more terms in a sum or difference. Good! BAD
