If a function f is differentiable in an interval I, i. What Byjus Class 7 Maths Ncert Solutions is integration? The formula that gives all anti derivatives is called the indefinite integral of the function and such process of finding anti derivatives is called integration. What is Integral Calculus? The development of integral calculus arises out of the efforts of solving the problems of the following types: a the problem of finding a function whenever its derivative is given, b the problem of finding the area bounded by the graph of a function under certain conditions.
These two problems lead to the two forms of the integrals, e. None of these Answer. Answer: C Thus, the determinant is a number associated to a square matrix. Hence, the correct answer is C.
