Implicit Differentiation

Category: Differential Calculus, Algebra

"Published in Suisun City, California, USA"

Find y" by implicit differentiation for


Solution:

Consider the given equation above


Since the given equation above is not a function, then we have to differentiate it by implicit differentiation as follows













but


or

then the above equation becomes







Rationalize the denominator in order to eliminate the radical sign at the denominator, we have







Take the derivative with respect to x, we have

















Rationalize the denominator in order to eliminate the radical sign at the denominator, we have


Therefore,
