In this question, we find the derivatives, using the chain's rule.
Doing this, the derivative is:
Chain Rule:
Suppose we have a function , and want to find it's derivative as function of t. It will be given by:
Thus, we have to find the desired derivatives, which are:
- w of x:
Considering
- w of y:
Considering
- w of z:
Considering
- Derivatives of x, y and z as functions of t:
- Derivative of w as function of t.
Now, we just replace what we found into the formula. So
Applying the multiplications:
Applying the simplifications:
Which is the derivative.
