FACTS ABOUT INTEGRAL CALCULUS

Image
The process of finding integrals is called  integration. The  equivalent word  of integration is Summation. Newton and Leibniz formulated the principles of Integration. The notation for the indefinite integral was introduced by  Leibniz. Leibniz adapted the integral symbol  " ∫"  from the letter "long s" in latin.     ( The long S stands for  summa- meaning - "  sum" or "total" ) The notation for the definite integral with limits above and below the integral sign was introduced by Fourier.   When limits are specified,    the integral is called a definite integral. When the limits are omitted, as in {\displaystyle \int f(x)\,dx,} the integral is called an indefinite integral,
