Question

Please help me understand this graph

Answer 1

How in the graph the time period changes as t+T/4 than t+T/2 than t+3T/4 and t+T

@Ashleyisakitty Can you help me with this ?

Answer 6

@TylerD can you help ????????

Answer 7

what class is this for

Answer 8

12th grade

Answer 9

at x and x+4vT the graphs of t+T/4 and t+3t/4 are at the midline

Answer 10

um...

Answer 11

time period looks same to me in all the waveforms

Answer 12

look there is nothing but a shift of origin of the sinusoidals
the second curve starts from that position where the first curve was at its t/4 th (in time axis)
so\[P_{f_2}(t+T/4)\]

so if the first one is
\[y_1=Asin \omega t \\then ~for ~the ~second ~one\\y_2=Asin(\omega t-T/4)\]
like that it will go on
like this--
the 3tr sine starts from that position where the first curve was at its T/2 so it is now
(t+T/2) means shifted by T/2
