# Deduction

Deduction:

Deduction is the conclusion

derived from data by a process

Definite integral:-

1.Definite integral as limit of sum

$\int^b_a \, f(x) \, dx\\ = (b - a ) lim \dfrac{1}{x} [ f (a) + f( a + b ) + ( an - \delta h]$

In the expression $\int^b_a \, f(x) \, dx$

a and b are  known as limits of integration,

f(x) is known as integrand and x

is known as variable of integration.
