To differentiate the given equation (x  \cos(x^2) + \frac{y^2}{x} + 3x^5 = 4x^3) with respect to (x), we follow these steps:

Differentiate each term of the equation with respect to (x), using the rules of differentiation.

Simplify the derivatives obtained in step 1.
Let's differentiate each term of the equation:

Differentiate (x) with respect to (x): [ \frac{d}{dx}(x) = 1 ]

Differentiate (\cos(x^2)) with respect to (x), using the chain rule: [ \frac{d}{dx}(\cos(x^2)) = (\sin(x^2))(2x) = 2x\sin(x^2) ]

Differentiate (\frac{y^2}{x}) with respect to (x), using the quotient rule: [ \frac{d}{dx}\left(\frac{y^2}{x}\right) = \frac{x(2y\frac{dy}{dx})  y^2(1)}{x^2} ]

Differentiate (3x^5) with respect to (x): [ \frac{d}{dx}(3x^5) = 15x^4 ]

Differentiate (4x^3) with respect to (x): [ \frac{d}{dx}(4x^3) = 12x^2 ]
Now, we'll substitute the derivatives obtained into the equation and simplify:
[ 1  2x\sin(x^2) + \frac{x(2y\frac{dy}{dx})  y^2}{x^2} + 15x^4 = 12x^2 ]
This equation represents the derivative of the given equation with respect to (x).

When evaluating a onesided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
