Trigonometric Function Question 1:
\(\lim_{x\rightarrow 0} \frac{(1-\cos 2x)(3+\cos x)}{x\tan 4x}\) এর মান কত?
Answer (Detailed Solution Below)
Trigonometric Function Question 1 Detailed Solution
গণনা
\(\lim \limits_{x\rightarrow 0} \dfrac{1-\cos 2x}{x(\tan 4x)}(3+\cos x)\)
⇒ \(\lim \limits_{x\rightarrow 0} 2\left(\dfrac{\sin x}{x}\right)^{2}.\dfrac{1}{4}\left(\dfrac{4x}{\tan 4x }\right)(3+\cos x)\)
⇒ \(2\times 1\times\dfrac{1}{4}\times 1\times(3+1)=2\)
অতএব, বিকল্প 3 সঠিক।
