મૂલ્ય શોધો. $\cos ec \left(-1410^{\circ}\right)$
It is known that the values of $cos ec$ $x$ repeat after an interval of $2 n$ or $360^{\circ} .$
$\therefore \cos ec \left(-1410^{\circ}\right)=\cos ec \left(-1410^{\circ}+4 \times 360^{\circ}\right)$
$=\cos ec \left(-1410^{\circ}+1440^{\circ}\right)$
$=\cos ec \,30^{\circ}=2$
જો $\sin \theta + \cos \theta = m$ અને $\sec \theta + {\rm{cosec}}\theta = n$, તો $n(m + 1)(m - 1) = $
$\cot \frac{\pi}{24}$ ની કિમંત મેળવો.
