Can someone help me with derivatives and chain rule... Find derivative of (t^3 + 1 )^(100) sqrt(1-x^2)

OpenStudy (anonymous):

\[(t ^{3} + 1)^{100}\]

OpenStudy (anonymous):

\[\sqrt{1-x ^{2}}\]

OpenStudy (anonymous):

So you first multiply everything on the inside of the parenthesis by 100 for the top equation and raise it to 100-1...Then you multiply all of that by the derivative of everything inside the parenthesis

OpenStudy (anonymous):

so it would be \[100(t ^{2}+1)^{99} x 2t\]

OpenStudy (anonymous):

\[100t ^{3} + 100\]

OpenStudy (anonymous):

where did you get x2t?

OpenStudy (anonymous):

x is multiplying- 2t is the derivative of what is inside the parenthesis

OpenStudy (anonymous):

can you explain how you got the derivative of the inside parenthesis adn explain about x

OpenStudy (anonymous):

Sorry, there is no x- i just used x to imply multiplication. The derivative of the inside is the derivative of t^2 which is 2t plus the derivative of 1 which is 0

OpenStudy (anonymous):

Oh ok so when you multiply through what do you get?

OpenStudy (anonymous):

200t(t ^{2}+1)^{99}

OpenStudy (anonymous):

\[200t(t ^{2}+1)^{99}\]

OpenStudy (anonymous):

I kept getting online \[300t^2(t^3 +1) ^(99)\]

OpenStudy (anonymous):

that is raised to 99

OpenStudy (anonymous):

Ah crap- i saw t^2 instead of t^3---that would be right then

OpenStudy (anonymous):

ok cool... what about the second one

OpenStudy (anonymous):

and how again did you get 2t as the inside derivative
