Solve deltaV=partialV/partialgammadeltagamma+partialV/partialkdeltah

$$\delta V = \frac { \partial V } { \partial \gamma } \delta \gamma + \frac { \partial V } { \partial k } \delta h$$

Solve for h

$$h\in \mathrm{R}$$

$$V=0\text{ or }\delta =0$$

Steps for Solving Linear Equation

Swap sides so that all variable terms are on the left hand side.

$$\frac{\mathrm{d}}{\mathrm{d}\gamma }(V)\delta \gamma +\frac{\mathrm{d}}{\mathrm{d}k}(V)\delta h=\delta V$$

Subtract \frac{\mathrm{d}}{\mathrm{d}\gamma }(V)\delta \gamma from both sides.

$$\frac{\mathrm{d}}{\mathrm{d}k}(V)\delta h=\delta V-\frac{\mathrm{d}}{\mathrm{d}\gamma }(V)\delta \gamma$$

Reorder the terms.

$$h\delta \frac{\mathrm{d}}{\mathrm{d}k}(V)=-\gamma \delta \frac{\mathrm{d}}{\mathrm{d}\gamma }(V)+V\delta$$

The equation is in standard form.

$$0=V\delta$$

This is false for any h.

$$h\in$$

Solve for V

$$\left\{\begin{matrix}\\V=0\text{, }&\text{unconditionally}\\V\in \mathrm{R}\text{, }&\delta =0\end{matrix}\right.$$
