In this problem,
Example Question #1322 : Calculus 3
Find where , ,
To find the derivative of the function with respect to t, we must use the multivariable chain rule, which states that
, where
Using this rule for both variables, we find that
, , ,
Taking the products according to the formula above, and remembering to rewrite x and y in terms of t, we get
Example Question #11 : Multi Variable Chain Rule
Find , where and ,
To find the derivative of the function with respect to t, we must use the multivariable chain rule, which states that for x. (We do the same for the rest of the variables, and add the products together.)
Using the above rule for both variables, we get
, , ,
Plugging all of this into the above formula, and remembering to rewrite x and y in terms of t, we get
Example Question #1323 : Calculus 3
Find , where
To find the derivative of the function, we must use the multivariable chain rule. For x, this states that . (We do the same for y and add the results for the total derivative.)
So, our derivatives are:
, , ,
Now, using the above formula and remembering to rewrite x and y in terms of t, we get
