I am being asked to find the derivative by what I think is the chain rule of this equation:
Let u be:
This is the part I am having trouble understanding. The formula for the derivative of is given as:
Is that the chain rule? How was calculated?
Thanks in advance...
If you want to use substitution, let and then and . So,
.
Then we apply the Chain Rule:
Notice that on the RHS, you are now differentiating with respect to (which is what you want).
Now, we plug back in for from our substitution:
So,
No. but that may be a typo.
Yes, that is the chain rule: if u is a function of f, then .This is the part I am having trouble understanding. The formula for the derivative of is given as:
Is that the chain rule? How was calculated?
Thanks in advance...
Here, so and .
Then .
