Can I just integrate straight away? I mean I already u-substitution already do I need to do another substitution?

So,I don't have to use trigonometric substitution?

I was doing a question using u substitution and at one point,I got sqrt(u-2). How do I integrate it further? Can I integrate is straight away with sqrt(u-2)(2/3) as answer or do I have to use trigonometric substitution? How to do if it's trigonometric?

I try to integrate. Looks like I make mistake and differentiate it. We integrate using integration by parts?

Integration of ln(x + x^2) is it (1+2x)/(x+x^2)?

When you said trigonometric substitution, you mean a^2-x^2=1-sin^2(x)?

Yes,it this one.I know U substitution, but I think I miss out something.How did you change u= \sqrt{2-x} to turn the integral into -2 \int \sqrt{2-u^2} du

How do I integrate sqrt(x/2-x)dx?

Thank you for your reply. Forgive me for being ignorance, but may I know what is an adapter plate and how does it look like. I google image and it seems to me they come in many shapes. Also, theoretically speaking, how does adapter plate work especially in my case for example, how will it help...

I am trying to convert all the heat dissipate by the heat sink into electricity by using thermionic converter. I plan to put my thermionic converter at the bottom of the heat sink fins. However, my thermionic converter is not big enough to cover the entire area of the heat sink fins. Is there...
