INTEGRAL CALCULUS – I (UNIT – 4 FOR NON – CIRCUIT AND UNIT – 5 FOR CIRCUIT)
Syllabus: Introduction: In differentiation, if a function is given, then we know how to find its derivative. Let us take up the reverse problem. i.e, if the derivative of a function is given, we can find the function. This is to find a function whose derivative is given as a function f(x). A function F(x)
