Leysa a^2+b^2=c^2

$$a ^ { 2 } + b ^ { 2 } = c ^ { 2 }$$

Leystu fyrir a (complex solution)

$$a=-\sqrt{c^{2}-b^{2}}$$

$$a=\sqrt{c^{2}-b^{2}}$$

Leystu fyrir b (complex solution)

$$b=-\sqrt{c^{2}-a^{2}}$$

$$b=\sqrt{c^{2}-a^{2}}$$

Leystu fyrir a

$$a=\sqrt{c^{2}-b^{2}}$$

$$a=-\sqrt{c^{2}-b^{2}}\text{, }|b|\leq |c|$$

Leystu fyrir b

$$b=\sqrt{c^{2}-a^{2}}$$

$$b=-\sqrt{c^{2}-a^{2}}\text{, }|a|\leq |c|$$
