A) n - 2f is a positive integral multiple of 3.
B) n - 2r is even
C) n - 2r is odd
D) None of the above
Correct Answer: A
Solution :
Suppose (s + 1) th term contains \[\sqrt{3}\]. Then, we have \[\int_{{}}^{{}}{\frac{1}{\sin \left( x-\frac{\pi }{3} \right)\cos x}dx}\] \[2\log \left| \sin x+\sin \left( x-\frac{\pi }{3} \right) \right|+C\] This will contain \[2\log \left| \sin x.\sin \left( x-\frac{\pi }{3} \right) \right|+C\]if \[2\log \left| \sin x-\sin \left( x-\frac{\pi }{3} \right) \right|+C\] \[{{x}^{2}}+\text{ }{{y}^{2}}=2{{a}^{2}}\]\[{{y}^{2}}=\text{ }8ax\]\[x=\pm (y+2a)\]\[y=\pm (x+2a)\] \[x=\pm (y+a)\]\[y=\pm (x+a)\]\[x+y+z=1\]\[2x+3y-z+4=0\] Hence, (n - 2r) is a positive integral multiple ofYou need to login to perform this action.
