My aim is to get a "cosine looking" curve rotated 45° counterclockwise.
When I graph : g(x)= x + cos(x) , I get a curve that has lost the nice and regular wavering of the ordinary f(x)= cos(x) curve.
Adding a coefficient does not work, but rather aggravates the change of form.
Is there a possible equation that would produce the curve I am aiming at?
Thanks for your help.
