The definite integral is an integral function that has a lower limit and an upper limit. It can be defined as the difference between the integrated values of a function obtained by substituting the upper limit value and the function value obtained by substituting the lower limit value. It has start and end values in the form of a closed interval. For example, for the definite integral function
∫ab f(x) dx
The start value is also known as a lower limit is ‘a’ and the end value is known as the upper limit is ‘b’. It can also be written as [a,b].
∫a∞ f(x) dx
c∫ f(x) dx
∫ab ∫xy f(x) dx
*Note- The same procedure is applicable for multiple integrals as well. Multiple Integrals are used in concepts taught in high-level mathematics and chemistry.
∫ab f(x) dx = - ∫ba f(X) dx
∫ac f(x) dx = ∫ab f(x) dx + ∫bc f(x) dx
∫ab p dx = p(b-a)
∫ab c . f(x) dx = c ∫ab f(x) dx
∫ab f(x) dx = ∫ab f(y) dy
∫ab f(x) dx ≤ ∫ab g(x) dx
∫ab [ f(x) + g(x)]dx = ∫ab f(x) dx + ∫ab g(x) dx
∫ab [ f(x) - g(x)]dx = ∫ab f(x) dx - ∫ab g(x) dx
∫ab [ f(x) / g(x)]dx = [∫ab f(x)dx] / [∫ab g(x)dx]
