Given 2 Integrals, How to solve other Integrals?
∫(2-5) f(x)dx=5 and ∫(4-5) f(x)dx=∏ , find
∫(5-5) f(x)dx =
∫(5-4) f(x)dx =
∫(2-4 f(x)dx =
Im going over old tests of mine to get ready for my final, and I cant find anywhere in my notes how I solved this, I originally got (a. 0 b. ∏ c. 5-∏). Can someone just explain the process of how to solve this. I understand b) by changing the sign and swapping the limits equals one of the given integrals, I just cant understand how I got A and C?
Thanks and Hi everyone

As for (c), it is just a linear combination of the first two integrals you were given. See if you can figure out in what way you can add/subtract the integrals to get (c).
Also, are there given limits of integration? You haven't listed them here, and without them it's not obvious that you need to swap them to get the result for (b) - without the limits of integration the answer could just as well be ##-\pi##.

b) That was a typo on my behalf, I had -∏ down
c) ∫(2-5) - ∫(4-5)
