Which of the following is NOT a property of definite integral?
1
\(\displaystyle\int_a^b f(x) dx =- \displaystyle\int_b^a f(x) dx\)
2
\(\displaystyle\int_0^a f(x) dx = \displaystyle\int_0^a f(a-x) dx\)
3
\(\displaystyle\int_0^{2a} f(x) dx = \displaystyle\int_0^{2a} f(2a-x) dx\)
4
\(\displaystyle\int_a^b f(x) dx = - \displaystyle\int_a^b f(t) dt\)
5
None of these
