u = (e^2x +1)well im actually having trouble with integrals. You know how you sub in u a section of the equation and then u find the derivative of u (du)? If the equation is [e^2x/(e^2x+1)^3]dx then what would i substiute in for u? i was thinking the demoninator but what would you put out in front of the integral to ballance itout? i hope this makes sense
i fucking hate diffyQs5y'''+2y''+.5y-6=tan^2(2x)
even i laughed at that.algerbra is hard?
wait til you get to germomerty or physerics
