Question

Describe how the graph of y=sinx has been shifted if the equation of the function is now y=5-3sin2(x+pie/2)

Answer 1

-The 5 is a constant, so it should be translated 5 units up.
-The -3 in front of sin means that the graph was reflected about the x axis, and has an amplitude of 3.
-The 2 in front of the angle means the period is double what it normally is (2 full cycles in 2pi
-The extra pi/2 inside the angle just means the graph started at x=pi/2 instead of the origin

Answer 2

X+pie/2 means the graph shift in the negative x direction by pi/2 units

Answer 3

oh, is it?

Answer 5

So what your trying to say is it's just cosine.. lol

Answer 6

Lol read further down ~~

Answer 7

Lol, OH MAN!
i clearly wasn't careful enough

Answer 8

haha you are tripping :P

Answer 9

jk :/

Answer 10

The things I could do to that function... but I can't do a phase shift

Answer 11

but i still dont know what the shift is . is it left 90 or does it go up or down at all ?

Answer 12

I think the first post is right, except for the phase shift correction

Answer 13

yea
