A) 10
B) 20
C) 1
D) 5
Correct Answer: A
Solution :
Given equation is \[y\,=\,5\,[\sin \,3\,\pi t\,+\,\sqrt{3\,\cos \,3\,\pi t}]\] or \[y\,=\,5\times 2\,\left[ \sin \,3\,\pi t\times \frac{1}{2}=\frac{\sqrt{3}}{2}\cos \,3\,\pi t \right]\] or \[y\,=\,10\,\sin \,\left( 3\pi t\frac{\pi }{3} \right)\]You need to login to perform this action.
