you never seen a sine wave? fucking liberals
sin(x)*3+1
3sin(x)+1
It's
Sin3(x)+1
4sin theta over pi?
OP here you are all wrong. Look at the 5 important points on the wave. The beginning point is up at (0,4); therefore, the wave is a cosine. Y=3cos(x-(pi/2))+1
If there were not points on this map then yes sin would work.
Wolfram Alpha says you are wrong. Argue with them. 3sin(x)+1 is the correct answer and conventional way to write it.
>mfw the x axis is in degrees, not radians
Nice troll, any such curve can be written as a sin or cos formula.
y = 3senx + 1
fug the pi looks like an x in the thumbnail
I dunno what you think you are on to here, but argue with wolfram rabbit face: wolframalpha.com
>cos(x-(pi/2))
that just moves the starting point of the curve you fucker, aka converts a sin to a cos
Graph it bub. Look at the points. If you graph a sin wave the origin point would be to the right of the y-axis; however, the sin shows the origin point high on the y-axis as well to the left; therefore, must be cosine. Right? If we are being technical. Which we are.
ah so that's what you were on to, hehe i get u now
sine starts at sine=0 at x=0 and goes positive. There's no need to offset a cosine by pi/2 (which makes it sine btw). [3*sin(x)] + 1 is correct, as already given.
Well, the final solution is to kill all the Jews.

i have never heard that convention before -- but that's just a convention, and the sin formula is a more concise way to write it. in my classes if they wanted sin or cos in particular they asked for it.
M=big
This just changes the amplitude and period, not starting point at all. The starting point is changed when -pi/2 is divided by 1/1 which is still -pi/2 so the period is shifted to the right pi/2
Fuck you OP im not doing your homework
I feel ya, and sin is correct, but not when it comes to the points labeled on the graph, which my uni teacher is ornery. I have an easier one for you guys.
wrong.
multiplying M * sin(x) changes the amplitude
multiplying sin( M * x) changes the period
subtracting sin(x - M) moves the starting point of the period
and since pi/2 is 1/4 of a period, it converts sin to cos, nigger read your textbook
Here you go, here is your equation.
(6*cos(x))+3
y = 3 cos(2x)

FUCK, i need to study again...
You are correct.
I agree with you there, thanks for the info.
underrated post
op is actually a fucktard. doesnt realize anything that can be represented in terms of sin can be represented in cos and vice versa.
Enjoy 10th grade little fella.
in case this isnt obvious
sin(x) = cos(x-pi/2)
ect, ect
you can write/convert all cos functions in sin, its just preference
How about this, what's the area under this "curve?"
