Question

y=sinx , y=sin3x draw the sketch of the above pair of functions

Answer 1

that 3 makes the wave compress or stretch

Answer 2

sir here in y=sin3x 2/3 pi is the period . how to draw the graph of y=sin3x is the main problem for meeeeeeeeeeeeeeeeeeeeeee

Answer 3

if x = 2pi, we would normally have one complete cycle

when x = 2pi/3 in the second one there we have complete a cycle in 1/3 the time

Answer 4

sr totally confused can u please draw it if u hv time

Answer 5

notice that the 3 indicates that we are moving 3 times as fast in a given normal period; so we squish the sin by a factor of 1/3

Answer 6

well thanks please check my answer i am posting

Answer 7

Please check the graph of y=sin3x

Answer 8

that looks more like a graph of y=sin(1.5x)

Answer 9

you need 3 complete cycles stuffed into a normal period of 2pi

Answer 10

youve only got 1 and a half cyles stuffed in there

Answer 11

how would i determine to make number of circles sir ? is it dependent on period or amplitude

Answer 12

i have attached the complete graph of y=sinx,y=sin3x on the same axes . is that one correct ?

Answer 13

you are still off on those

Answer 14

why sir ?

Answer 15

well, for starter, your sin x (which is spose to be drawn normal) is going factter than the sin 3x (which is faster).

Answer 16

i drew you a picture

Answer 17

this one sir ? http://assets.openstudy.com/updates/attachments/4f75d709e4b0f07ddab1c77b-amistre64-1333123622987-untitled.png

Answer 18

yep, that the one

Answer 19

notice how there are 3 sins in the same space as 1 sin?

Answer 20

sir drew 1 circle of y=sin3x and y=sinx has 3 circles

Answer 21

lol, thats not a sketch :P

Answer 22

ok sir if there was sin6x then there would be 6 circles for sin6x correct ?

Answer 23

there would be 6 sin waves stuffed into one regular period, yes; not 6 cycles, but 1/6 of a cycle for each one

Answer 24

the period is 2pi/n where n is the multiplier. in this case n=6

Answer 25

thanks sir sorry for irritating u in questions line. Actually i have just started 11th grade but m in 9th one. derfore facing some problems
well i wnt to share a result with u
result of my 8th class just came and i topped the secondary section 6th -12th classes with 10 cgpa it meaans A1 in all subjects

Answer 26

ill assume thats a good thing :)

Answer 27

well is there any graph software ?
