Solve -y/-1

$$\frac{ -y }{ -1 }$$

Evaluate

$$y$$

Solution Steps

Anything divided by -1 gives its opposite.

$$-\left(-y\right)$$

Multiply -1 and -1 to get 1.

$$y$$

Differentiate w.r.t. y

$$1$$

Steps Using Definition of a Derivative

Anything divided by -1 gives its opposite.

$$\frac{\mathrm{d}}{\mathrm{d}y}(-\left(-y\right))$$

Multiply -1 and -1 to get 1.

$$\frac{\mathrm{d}}{\mathrm{d}y}(y)$$

The derivative of ax^{n} is nax^{n-1}.

$$y^{1-1}$$

Subtract 1 from 1.

$$y^{0}$$

For any term t except 0, t^{0}=1.

$$1$$
