First we write px + q = a (d(√(ax 2 + bx + c))/dx) + b En los próximos días y semanas, analizaremos los temas que conciernen a la materia de cálculo integral, estos temas son teóricos y prácticos al mismo tiempo, puesto que, se deben resolver problemas de integrales. Suppose f x( ) is continuous on [ab,]. The formula sheet of integration include basic integral formulas, integration by parts and partial fraction, area as a sum and properties of definite integral.at first take a look at indefinite integration.
