$\frac{5}{2 \sqrt{6}}$

Vedclass · Answer

(D) આપણે જાણીએ છીએ કે $\cosh x = \sqrt{1 + \sinh^2 x}$.આપેલ છે કે $\sinh x = \frac{5}{12}$,તેથી $\cosh x = \sqrt{1 + (\frac{5}{12})^2} = \sqrt{1 + \frac{25}{144}} = \sqrt{\frac{169}{144}} = \frac{13}{12}$.નિત્યસમ $\cosh x = 2 \cosh^2 \frac{x}{2} - 1$ નો ઉપયોગ કરતા:$2 \cosh^2 \frac{x}{2} - 1 = \frac{13}{12}$$2 \cosh^2 \frac{x}{2} = \frac{13}{12} + 1 = \frac{25}{12}$$\cosh^2 \frac{x}{2} = \frac{25}{24}$$\cosh \frac{x}{2} = \sqrt{\frac{25}{24}} = \frac{5}{2 \sqrt{6}}$.

જો $\sinh x = \frac{5}{12}$ હોય,તો $\cosh \frac{x}{2} =$
