Answer 1

Can anyone help?

Answer 2

do you know sin(x) graph?

Answer 3

yes

Answer 4

I just looked it up pn google but I need help with the transformation

Answer 5

on*

Answer 6

what's differ between this graph on your link and graph of y=sin(x)?

Answer 7

its more narrower I guess
but can you tell me the exact transformations?

Answer 8

you just need answer? ;-)

Answer 9

yes

Answer 10

just the transformations

Answer 11

y=2sin(3x)

Answer 12

thats the equation?

Answer 13

ohom, if draw it, you can see your graphs in your link ;-)

Answer 14

what?

Answer 15

@mhmdrz91 are u sure that its of sin(3x)?
its an inverted cosine pattern sin(x + 90+180) which is sin(x+270) as far as the angle is concerned and for magnitude multiply it by 2

Answer 16

I dint write the transformations directly there btw

Answer 17

I need the transformations !

Answer 18

what are the transformations for converting sin(x) to cos(x)?? @cupcakezz

Answer 19

idk

Answer 21

@SandeepReddy no! it's y=-2sin(3x) :D

Answer 22

you are expected to learn the concepts , not the answers for a particular problem.
Sin and cosine are the fundamental trigonometric identities that will not only come in math but also in other sciences and subjects ( even in biology) everywhere,
so be perfect in them first.
you should be atleast in a position to identify a cosine curve from sine curve

Answer 23

@mhmdrz91 what makes u think that is an answer?

Answer 25

@mhmdrz you are right, i'm sorry i overlooked

Answer 26

@mhmdrz91 thanx fr opening my eyes :)

Answer 27

@SandeepReddy :)) Opening your eyes? :P kidding me? :P
have nice time ;)
