i know this is a very self indulgent thread but i will delete it as soon as i get the help i need we had this take home quiz on derivatives and im lost Y=e^(x^7 -4x^5 - 1) would this just be the same thing for the derivative since the der. of e^x = e^x? or would it be something like (7x^6 - 20x^4) ( e^ x^7 -4x^5 -1)? also y= log (x^2 + x +9) no idea what im doin on this one thanks for any help
The first one should be chain rule, so e^u * u' like you said. For the second one ln x = 1/x and apply the chain rule there as well. Not completely sure though. I'm taking calc as well.
you did that one correct. chain rule thats also right. chain tule on 1/x=lnx btw, dont go onto clac 2 unless you really need it. i hated that class
im taking calculus as well.. high school tho. like others have said before use the chain rule...other than that i have no clue. we arent this far yet. calculus is hella fun tho. i love math that can be applied to real life situations
umm yea i dont think that would go over to well we had a little...verbal confrontation about a month ago
