Question 258293
the graph of this equation will look like this:


{{{ graph(600,600,-10,10,-4,4,cos((-1/4)(x+(3.14/3)))+2) }}}


the values along the x-axis are radians.


the values along the y-axis are your answer.


you can translae radians to degrees as follows:


degrees = radians * 57.29577951


example:


when x = 6.283185307, then degrees = 6.283185307 * 57.29577951 = 360.
