I dont understand this because when I find the intersection points which is x=0 and x=1 , how do I know which is the outer and lower function ?

Find the area bounded by the curve: y = x(x-1)^2, the line y = 2, and the y - axis

How do I do this ?

Basically what the questions states. Thanks

∫ (1)/(sqrt(52x -1))dx Please show me steps. Im having a hard time figuring this out

I'm having a lot of trouble with the set up and integration. Please help me with this problem, thank you. I know you are supposed to use the formula integral(2pi * y * sqrt(1+(y')^2)).

∫dx/(50-10x)=-1/10ln[50-10x]+c Why does factoring 1/10 a constant out of integral not work. ∫dx/(50-10x)=1/10∫dx/(5-x) u=5-x du=-1 -1/10ln[5-x]...

∫dx/(50-10x)=? Does factoring out 1/10 change the answer.

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:...
