I will just do the first term 1) When you are taking chain rule always takes derivative of outside function first
2) derivative of outside function is 3(t^4-1)^2 derivative of inside function is 4t^3 multiply inside and outside derivative
This is a chain rule problem and a product rule. So be careful.. if you don't get it reply.
I don't get it haha.
Yes I know but he just wanted help with chain rule so I used the first term as example
i'm actually a she. Since it is a product rule how would i find in the outside and inside function?
You will have to use both product rule and chain rule to solve whole problem. The product rule is = F(x)'g(x)+g(x)'(F(x)
In your function you have two things mutliplied together.
okay, let me try and figure it out. thanks
How is going there?
okay, so i got the derivative of the first one, which was the same as you got. and i ended up with a long equation.
Yes it's pretty messy if you don't simplify it. i can tell you the answer if you think you got it or you're stumped
Here how I would solve it
applying product rule (t^4-1)^3)* 4(t^3+1)^3 * 3t^2 + (t^3+1)^4 *3(t^4-1)^2 *4t^3 From here it is just algebra
If It is not a word problem, you can leave it here
im so confused! okay so after i take the derivative of the outside functions, what do i do? i ended up with 3(t^4-1)^2 (t^3+1)^4 + (t^4-1)^2 [4(t^3+1)^3]
You left out derivative of inside function
