Question: $ \int_{{}}^{{}}{(3,cose{c^{2}}x+2\sin 3x)\ dx=} $
[AI CBSE 1981]
Options:
A) $ 3\cot x+\frac{2}{3}\cos 3x+c $
B) $ -( 3\cot x+\frac{2}{3}\cos 3x )+c $
C) $ 3\cot x-\frac{2}{3}\cos 3x+c $
D) None of these
Show Answer
Answer:
Correct Answer: B
Solution:
$ \int_{{}}^{{}}{(3cose{c^{2}}x+2\sin 3x),dx} $ $ =-3\cot x-\frac{2\cos 3x}{3}+c=-,[3\cot x+\frac{2}{3}\cos 3x]+c. $
