Question

Find the derivative of each funtion and show work:

1. f(x)= cos(3x^2+2x+1)

2. f(x)=(3x+1) multiplied by square root (x^2+1)

3. f(x)= sin^2(tan 3x)

Answer 1

-(3x +2)sin(3x^2 + 2x +1)

Answer 2

(6/(1+3x)) * sin(tan3x)cos(tan3x)

Answer 3

o messed up first one should be -(6x +2)sin(3x^2 + 2x +1)

Answer 4

What rule are you using?

Answer 5

(2x/(x^2+1)) (3x+1) + 3 * sqrt(x^2+1

Answer 6

might have messed up somewhere in there. doing em in my head

Answer 7

yeah rub it in, lol, i cant even do em on paper

Answer 8

chain rule on first, chain + product rule on 2nd and 3rd

Answer 9

i cant even telle which ones which any more lol. You didnt number em

Answer 10

? gonna have to meet me half way man
you have the answer... think a little

Answer 11

-(6x +2)sin(3x^2 + 2x +1) kinda looks like the first equation aye

Answer 12

yeah then the one with 2x/x^2+1 is the second right

Answer 13

(6/(1+3x)) * sin(tan3x)cos(tan3x) has a tan so it's prob the 3rd one

Answer 14

then the third is the is the one with lots of trig functions right

Answer 15

(2x/(x^2+1)) (3x+1) + 3 * sqrt(x^2+1 has a sqrt so it's prob the 2nd

Answer 16

thats what i figured just got all jumbled up

Answer 17

are going going to be taking cal 2 + cal 3 in the future?

Answer 18

if so, you should really sit down and spend some time learning mathematica. It will help you a ttooooon with calculus. you can solve most of the problems, and check answers easily with it

Answer 19

Actually i am taking calc 1 right now, and my teacher got behind and sent us home with a take home test and said figure it out. Its due today at 5pmEatern time. And i just got off work at 7am and have been working on it all morning, and trying to find ppl to help explain all this to me because he didnt teach it

Answer 20

what is mathematica?

Answer 21

that and, check out patrickjmt's tutorials on youtube. he's a beast

just type in the search something like "patrickjmt chain rule" (without the quotes)

Answer 22

mathematica is a math program that will literally solve all of these equations for you. they even have a web based version online. google wolfram mathematica alpha. On some stuff, alpha will even show you all of the steps to get the answer

Answer 23

interesting, yeah i have to get this test done in the next 5 hours or im screwed,, so im going to check out that site.
If you interested in doing some more calc problems i can send you some more lol. I am gonna check out some youtube videos by that person you said too!

Answer 24

gotta go to class
upload them real fast and i'll plug them into mathematica for you

Answer 25

eh well nm, just post them. There are a ton of people on here that will help with cal 1 stuff

Answer 26

ugh send me your email and ill email them cause its kinda long

Answer 27

would help ya out but i have to catch a buss in 6 min

Answer 28

o ok well have a good day at school thanks for the help

Answer 29

no problem

Answer 30

gl on your test

Answer 31
