Solve dz/droperatorname{dan}dz/dθtext{jika}z=tan^-1(x/y)

$$\frac { d z } { d r } \operatorname { dan } \frac { d z } { d \theta } \text { jika } z = \tan ^ { - 1 } ( \frac { x } { y } )$$

Solve for d

$$d\in \mathrm{C}$$

$$x=0\text{ and }y\neq 0$$

Steps for Solving Linear Equation

Multiply a and a to get a^{2}.

$$\frac{\mathrm{d}(z)}{\mathrm{d}r}da^{2}n\frac{\mathrm{d}(z)}{\mathrm{d}\theta }jikz=\arctan(\frac{x}{y})$$

The equation is in standard form.

$$0=\arctan(\frac{x}{y})$$

This is false for any d.

$$d\in$$

Solve for a

$$a\in \mathrm{C}$$

$$x=0\text{ and }y\neq 0$$
