So basically I have a table of points , and im supposed to find the equation of sine and cosine from it. How would i do that?
so for cos, y= AcosB(x-C)+D
and to find the D for cos, it's highest y value - lowest y value right?
and to find A it's highest - D ?
how would you find C %26amp; B?
%26amp; for sin, y=AsinB(x-C)+D ?
how do i find the A\B\C\D for that?
How to find the equation for sine\cosine ?
Sorry, I can't make any sense out of your question. In particular, "to find the D for cos, it's highest y value - lowest y value right? and to find A it's highest - D ?" is particularly cryptic.
You say you have a table of points--I presume that means values of (x,y) where x and y satisfy the equation.
Maybe you're supposed to plug those into the equation to get at least 4 equations for the unknowns ABCD and then solve for their values.
