A) 4 and \[-\,\,4\]
B) 16 and \[-\,\,16\]
C) \[4\sqrt{2}\]and \[-\,\,4\sqrt{2}\]
D) None of these
Correct Answer: C
Solution :
Here, \[8\sin \theta \cos \theta +4\cos 2\theta =4\sin 2\theta +4\cos 2\theta \] So, maximum value\[=\sqrt{{{4}^{2}}+{{4}^{2}}}=4\sqrt{2}\] and minimum value \[=-\,\,\sqrt{{{4}^{2}}+{{4}^{2}}}=-\,\,4\sqrt{2}\]You need to login to perform this action.
