thanks alot dude! i got real distracted by my stats course for a week and went back to calc and was sort of baffled lol. really helped me remember what i learned.

ops, i thought you meant find derivative
patrickJMT (November 30, 1999 at 12:00 am)
no problem!

Wow these are awesome!!! :D Thanks!!

i guess you could use logarithmic differentiation a whole bunch...

Hi Patrick how can i do to integrate this: e^x^x^x Thanks Patrick!

Yo buddy, regarding the last integral: If you differentiate that final result of yours aka the primitive function of x*3:d√(x+4) you will obtain (x+4)^(4/3)-4*(x+4)^(1/3) wich ≠ x*3:d√(x+4). I used partial integration on this one and got my answer to F(x)=(3/7)*(x+4)^(4/3)*(-3+x). But ofc I' human so i might be seriously wrong. Plz check this for me. thanx in advance!

I did it! I did all the integrals here by myself! Cool =)

great video very clear! just to mention that to others who is watching this video, the question involving 2 substitutions does not necesserily need 2 subs, u^2=1-x^2 gives same answer. |
