To implicitly differentiate ( -1 = \sin(x+y) ), we'll differentiate both sides of the equation with respect to ( x ) treating ( y ) as a function of ( x ).

Apply the chain rule for the left side and the chain rule and the derivative of sine function for the right side.

The derivative of (-1) with respect to (x) is (0).

The derivative of (\sin(x+y)) with respect to (x) involves the chain rule: [ \frac{d}{dx}(\sin(x+y)) = \cos(x+y) \cdot \frac{d}{dx}(x+y) ]

[ = \cos(x+y) \cdot (1 + \frac{dy}{dx}) ]

Thus, the implicit derivative of ( -1 = \sin(x+y) ) with respect to ( x ) is:

[ 0 = \cos(x+y) \cdot (1 + \frac{dy}{dx}) ]

Solve for ( \frac{dy}{dx} ) if necessary.

When evaluating a one-sided 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.
