find the integral 1/ (x* e^x ) dx

I have an integral with ∫ (b=0, a=-1) and the inside function is (2t)/[(3+t2)3]dt. The directions tell me to "Evaluate the definite integral by making a u-substitution and integrating...

Evaluate the integral (1/sqrt(x^2 - 5))dx on limits of 3 to 4, using the formula: integral of (1/sqrt(x^2 - a^2))dx. Recall that this formula was found by using the substitution x = a cosh t,...

∫∫∫w (1-z2) dxdydz ; W is the pyramid with the top vertex at (0,0,1) and base vertices at (0,0,0),(1,0,0),(0,1,0),and (1,1,0). How would I set up the bounds of the integral??

Can someone help me solve for this indefinite integral?: (u^2 + u)/(2u^3 + 3u^2 + 1)^(2/3) Thank you!

I need help solving a couple of indefinite/definite integrals. It seems all of my homework problems have done the less complicated ones so I'm not sure how to do these ones: First problem:...

What is the definite ∫((x2-3x+2)/(x+1)) ? I tried dividing this but I didn't know what to do with the remainder.

The curve is x^3-6x^2+11x-6. I have to prove that the two regions enclosed between the x-axis and the curve are equal. Given is, that the curve cuts the x-axis at x=1,x=2 and x=3. I tried finding...

1. Evaluate the integral S-12 f(x)dx, when f(x)=3-x3 when x is less than or equal to 1; f(x)=x2 when x is greater than one. 2. Evaluate the integrals using the FTC 1. (a)...

Draw the level curves for the function f(x,y) = x^2+y-3, first for z=1 and then for z=6. Use the same grid for both curves. All intercepts should be marked with their coordinates.
