Integral Calculus

This chapter introduces the method of integration. It covers concepts such as substitution method, indefinite integration, integration by parts, integration by partial fraction-factors, definite integrals, and definite integral as a limit of a sum.

The chapter introduces the concept of definite integrals and states that they have unique values. It is introduced as the limit of a sum. If it has an anti-derivative in the interval, its value is the difference between the values at the endpoints.

This chapter explains the area under the curve, area bounded by the curve, axis and given lines, and area bounded by two curves. The volume of solid of revolution, volume of solid obtained by revolving the area under the curve is also discussed here.

This chapter covers topics, such as, Basics of Differential Equation,Order and Degree of a Differential Equation,Formation of a Differential Equation,Solution of a Differential Equation,Methods of Solving of a Differential Equation etc.
