When I substitute u=x^2-5x+25 I get du=2x-5 dx. That gets me close to x dx. I would normally just pull out 1/2, but I'm confused how to deal with the -5. it looks like I should get a ln...

Using the substitution x=(√3)tany find the exact value of 1∫3 1/√(3+x^2) dx expressing your answer as a single logarithm in terms of y
I've been stuck on this question for a while. I've tried integration by parts but that doesn't help so I thought substitution would help but I don't know what to substitute it for.
The slope of the curve has to be found by the dy/dx= 6/x^2. It will most likely end up as a y-y1=m(x-x1) formula at the end.
find the volume of the solid formed by rotating the region enclosed by x=0, x=1, y=0, y=9+x^7 about the y axis

Every month, a particular interest-bearing account earns 0.2 percent interest on the average balance for that month. The function B(t) =7.5t^2 -300t +5000 represents one investor's balance...
∫dx/(c-k/x)1/2
At what value of x is f(x) a minimum? I know f'(x) = e^((x^2-3x)^2) , but I don't know how to continue. Thanks!
I'm in a hurry to find the answer. Please help me. Thanks so much
