Solve psiv^0

$$\psi v ^ { 0 }$$

Evaluate

$$\psi$$

Solution Steps

Calculate v to the power of 0 and get 1.

$$\psi \times 1$$

For any term t, t\times 1=t and 1t=t.

$$\psi$$

Differentiate w.r.t. ψ

$$1$$

Steps Using Definition of a Derivative

Calculate v to the power of 0 and get 1.

$$\frac{\mathrm{d}}{\mathrm{d}\psi }(\psi \times 1)$$

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

$$\psi ^{1-1}$$

Subtract 1 from 1.

$$\psi ^{0}$$

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

$$1$$
