    Friction and Acceleration: Solving for the Motion of a Moving Sculpture

    fnet = ma you need to figure out your acceleration, then prove with a static equation that you have enough fnet to overcome mu static. Then use mu kinetic to determine the acceleration of the sculpture relative to the van. I don't remember the equations right off hand, but with a couple of...

    Integrating Definite Integral: sqrt2 to 2 1/x^3*sqrt(x^2-1)dx

    what would x^3 be in terms of u? I'm going to have to head to a tutor and have someone walk me through this one.

    Integrating Definite Integral: sqrt2 to 2 1/x^3*sqrt(x^2-1)dx

    ok. do you mean to say substitute u^2=x^2 -1 to get rid of the sqrt then? i just don't understand how that helps me. I end up with variables x and u in the denominator then.

    Integrating Definite Integral: sqrt2 to 2 1/x^3*sqrt(x^2-1)dx

    Ok, was i correct in splitting it into two integrals? I'm having a lot of difficulty on this one. I got an answer, but it's really long and seems wrong. I found I'm supposed to get but need to be able to work through this problem. How i got mine was for the second part used x = sec...

    Integrating Definite Integral: sqrt2 to 2 1/x^3*sqrt(x^2-1)dx

    for some reason this forum isn't working, and i didn't mean to repost several times... I hit refresh a couple times and that's what happened. I apologize!

    Integrating Problem: Definite Integral from sqrt2 to 2

    Homework Statement i'm taking a defitinite integral from sqrt2 to 2 of the function 1/x^3*sqrt(x^2-1)dx. Homework Equations The Attempt at a Solution I separated it into 1/x^3 and 1/sqrt(x^2-1). I have the second part using trig sub. as being sec theta dtheta, before integrating...

    Help with U Substitution for integral of cos(pi/x^11) / x^12

    it looks like i did, i forgot the derivate of pi was zero, haha. dumb on my part. but that doesn't get me anywhere because no where in the original problem is the du. i have to get rid of that 1/x^12 somehow.

    Help with U Substitution for integral of cos(pi/x^11) / x^12

    problem with that is when you take the derivative, you don't have the dx int he problem. i'm almost certain the U has to equal x^12 as then du would then be 11x^11 and you can divide that by 11 and stick a 1/11 out front. I just don't know how to get du out of that stupid fraction. unless I'm...
