(B) આપેલ છે,$\lim _{x ightarrow 0} \frac{1-\cos 2 x}{x 	an 2 x+\frac{2 x}{3} 	an 3 x}$ નિત્યસમ $1-\cos 2x = 2 \sin^2 x$ નો ઉપયોગ કરતા: $= \lim _{x ightarrow 0} \frac{2 \sin^2 x}{x 	an 2 x + \frac{2 x}{3} 	an 3 x}$ અંશ અને છેદને $x^2$ વડે ભાગતા: $= \lim _{x ightarrow 0} \frac{2 (\frac{\sin x}{x})^2}{\frac{	an 2 x}{x} + \frac{2}{3} \frac{	an 3 x}{x}}$ $= \lim _{x ightarrow 0} \frac{2 (\frac{\sin x}{x})^2}{2 (\frac{	an 2 x}{2 x}) + 2 (\frac{	an 3 x}{3 x})}$ $\lim _{x ightarrow 0} \frac{\sin x}{x} = 1$ અને $\lim _{x ightarrow 0} \frac{	an kx}{kx} = 1$ નો ઉપયોગ કરતા: $= \frac{2(1)^2}{2(1) + 2(1)} = \frac{2}{2+2} = \frac{2}{4} = \frac{1}{2}$

$\lim _{x \rightarrow 0} \frac{(1-\cos 2 x)}{x \tan 2 x+\frac{2 x}{3} \tan 3 x} = $
