y=4sin(3X+Pie/4)-2

what determines the period and phase shift?

I know that 4=Amplitude

The answer in the back of the text book says

Period=2pie/3

Phase Shift=-pie/12

standard form:

[tex]A\sin (kx+\phi)[/tex]

period is given by [tex]2\pi/k[/tex]

[tex]A\sin (kx+\phi)[/tex]

period is given by [tex]2\pi/k[/tex]

Yeah but i think it is better to do it this way, because not always you can immediately determine the period of a function based on that standard form. I think it is better to first know how to come up to that standard form.

so how do we know whether a function is periodic or not?

f(x+T)=f(x), where T is the period.

so after you substitute these values you will be able to find the period of that function, which is the same as ry122 said on his op.

dessert =/= a mathematical constant, Ry
