Question

Which of the following functions of time represent
A)Periodic motion
B)Non periodic motion
Give the time period in each case
(w is any +ve constant...)

Answer 1

\[\LARGE \sin wt+\cos wt\]

Answer 2

\[\LARGE \sin wt+\cos2wt+\sin4wt\]

Answer 3

\[\LARGE e^{-wt} \]

Answer 4

and log(wt)

Answer 5

*

Answer 6

Did the * mean you don't know or you tagged yourself ?O_o

Answer 7

@Mashy @shubhamsrg

Answer 8

sinwt + sin(pi/2 -wt)
2 sin(pi/4) cos(pi/2 -2wt)
2sin(pi.4) sin(2w)t

T = 2pi/2w

Answer 9

I applied the formula wrong
hmm

Answer 10

it'll be
2sin(pi/4) cos(pi/4 - wt)

Answer 11

T = 2pi/w

Answer 12

1 ,2 periodic.. 3 ,4 non periodic :p
