Honestly, Thank you sooo much for these videos. Even though some of them may not be getting much attention, but I absolutely love this channel when I can just surf through everything when I need help with Chemistry or Math.

BROOO, I stayed up late yesterday and spent like 3 hours trying to figure out a similar problem to this, to end up watching this and figuring it out at 6:36am at Landry mat on my phone…..

Integration of 1/(x^2+a^2) is the identity where a is 1

Brother i think u made a mistake cause 1/x²+1 is simply= 1/2 loge[x-1/x+1] according to 12th formulas so the answer would be x-1/2Loge[x-1/x+1] .

Cant you just use the product of x^2 and knowledge that 1/(1+x^2) is the derivative of tanx?
