Solve h^2=c_1^2+c^2

$$h ^ { 2 } = c _ { 1 } ^ { 2 } + c ^ { 2 }$$

Solve for c (complex solution)

$$c=-\sqrt{h^{2}-c_{1}^{2}}$$

$$c=\sqrt{h^{2}-c_{1}^{2}}$$

Solve for c_1 (complex solution)

$$c_{1}=-\sqrt{h^{2}-c^{2}}$$

$$c_{1}=\sqrt{h^{2}-c^{2}}$$

Solve for c

$$c=\sqrt{h^{2}-c_{1}^{2}}$$

$$c=-\sqrt{h^{2}-c_{1}^{2}}\text{, }|h|\geq |c_{1}|$$

Solve for c_1

$$c_{1}=\sqrt{h^{2}-c^{2}}$$

$$c_{1}=-\sqrt{h^{2}-c^{2}}\text{, }|h|\geq |c|$$
