, \(\frac{\sin ^2 A}{1-\cos A}=x\) എന്ന് കരുതുക
ഉപയോഗിച്ച സൂത്രവാക്യം:
- sin2A = 1- cos2A
- a2-b2=(a+b)(a-b)
കണക്കുകൂട്ടലുകൾ :
\(\frac{\sin ^2 A}{1-\cos A}=x\)
\( x = \frac{\sin ^2 A}{1-\cos A} = \frac{(1+cos A )(1-\cos A) }{(1-\cos A)} =1+cos A \)
x =cos A + 1
അതിനാൽ, \(\bf \frac{\sin ^2 A}{1-\cos A} =1+cos A \: \).
