It was dx but then we substituted it to du, no?

Okay, went back to my textbook. This should be the way to simplify the denominator, right?

/ Just take the radical of the values like this?

Raising both denominator and numerator to the power of two?

Uhm, is this any better?

So the final integral should look something like this? This does seem very complicated to solve though!

It should be 3?

I really don't know. I have trouble reconciling the two parts. I guess we could substitute x with asinh?

Okay, I tried to correct the previous mistakes, Hope this one is good? Thank you

Homework Statement Homework Equations So the question is asking to solve an integral and to use the answer of that integral to find an additional integral. With part a, I don't have much problem, but then I don't know how to apply the answer from it to part b. I know I should subsitute all...

Homework Statement [/B] Homework Equations Drawing a diagram for the forces is the easy part. I am not sure I am doing the equation of the sum of the torques well. The Attempt at a Solution This is my attempt for the forces[/B] And this for the torques:

No, my calculator gave me the number 1.3 because it wasn't set to linear calculations. It gave me fractions!

Why doesn't my calculator give me the same value?

Wait, so 1,333 is not valid? Because if I use 1.3 the different values of t don't match. But if I use 1.333 they match.

Okay, I think I got it now. The thing is when I put 24/18 in my calculator it gives me 1.3, not 1.333. That's the origin of the confusion I guess
