# Integration

You will learn the definition of integration by Riemann sums. Then we will discuss the fundamental theorem of calculus to define the relation between integral and derivative.

### Rules of calculation for integration - part 1

Speed is the derivative of distance travelled. Using the Fundamental Theorem of Calculus it follows that distance travelled is the integral of speed as a function of time. Using this example you will understand the rules of calculation for integration, when the integrand is multiplied by a constant or two integrands are added.

### Summary about integration

What is the definition of integration ? How are integration and differentiation linked through the fundamental theorem of Calculus? What are the rules of calculation for evaluating integrals? This video gives the summary of week 6 of the edX course: pre-university Calculus (Calc001x).
