Differentiate:

(6-xe^x)/(x+e^x)=...

Evaluate Intergral:

(2u^5-8u^3+5u^2)du, from lower limit -1 to higher limit 0.

(i got 10/3 for some reason...)

(u^7+6u^13)/u^9 du, from lower limit 1 to higher limit 2.

(n i got 47 for this..)

I tried these a few times but my answer is still not quite right, so im kinda stuck right now, can any1 help with the answers?
