Hey, can somebody please help me with this question: Two long parallel conductors carry equal currents in opposite directions. The force between them is 3F. The current in one of the conductors is doubled, but the current in the other is reduced to a third of its original value. The...

Hey, can anybody please help me with an Integration question. Its from the Cambridge book, diagnostic test, p175 Here it is: a) Show that [integral of f(X) with limits a and 0] = [int of f(a-x) with limits a to 0] This bit is fine. b) Hence show that: { Int of [ (cosX) / (cosX...

Can somebody look at my solution for this question and point out where I'm going wrong? The answer is [(square root of 5) - 1 ] Q: find integral of: X / {sq root(1 + X^2)} My solution: let u =X^2 du=2X dx at X=2, u=4 and at X=0, u=0 Therefore integral becomes (with limits 4...
