camr_on replylemmy.worldNever heard of this before, looks cool. Wish I had that when I was taking calculus lol4Reply
CelloMike replystartrek.websiteJust x²+c, but when you're integrating between limits the +c doesn't matter - so you're just left with the difference between 13² and 10²...16Reply
zzigmus64 replylemmy.world1Hide 1 replyThe integral of 2xdx is x^2 + c, and it’s evaluated from 10 to 13. So you’d have the following: (13^2 + c) - (10^2 + c). The c’s cancel. I’ll leave you to do the rest…11Reply

Nice.

Is this Wolfram Alpha?
It is Photomath
