can someone please help me with these equations of definite integrals in integration?
∫ x/sqrt 2x  1 dx from 5 to 1
∫ e^3/x//x^2 dx from 3 to 1  this is e to the power 3 over x, all over x squared. I hope that makes sense.

Best ResponseYou've already chosen the best response.0regarding e^(3/x)/x^2 the derivative of 3/x is is 3/x^2 so let use substitution u=3/x du= 3/x^2 now we can do integral e^(u)*du take out the 1/3 ofcouse. so you should have \[1/3\int\limits_{?}^{?} e^udu \] that should push you thou now sure about my answer:D but hope i helped
