Prove that, int (e^(x))/(x^(4))dx=-(e^(x))/(3)[(1)/(x^(3))+(1)/(2x^(2))+(1)/(2x)]+(1)/(6)int (e^(x))/(x)dx .

Evaluate the integerals. int e ^(x) log (e ^(2x) +5e^(x) +6)dx on R.

If f(x) = (1)/(sqrt( (x+1) (e^(x) - 1)(x-4)(x +5)(x -6))) , then the domain of f(x) is

Let f(x) = 5x^(6) + 18x^(5) + 15x^(4) - 10 ,then which of the following is/are true?
