حل T=2pisqrt{h^2+k^2/2gh}

$$T = 2 \pi \sqrt { \frac { h ^ { 2 } + k ^ { 2 } } { 2 g h } }$$

حل مسائل T

$$T=\pi \sqrt{\frac{2\left(h^{2}+k^{2}\right)}{gh}}$$

$$\left(g<0\text{ and }h<0\right)\text{ or }\left(h>0\text{ and }g>0\right)$$

حل مسائل g

$$g=\frac{2\times \left(\frac{\pi }{T}\right)^{2}\left(h^{2}+k^{2}\right)}{h}$$

$$T>0\text{ and }h\neq 0$$
