To derive the cos(x-1) formula, we start with the definition of cosine as the ratio of the adjacent side to the hypotenuse in a right-angled triangle. We then use the angle subtraction formula for cosine, which states that cos(A-B) = cos(A)cos(B) + sin(A)sin(B). By applying this formula to the expression cos(x-1), we can simplify it to cos(x-1) = cos(x)cos(1) + sin(x)sin(1).

If you're interested in learning more about the cos(x-1) formula and its applications, we recommend exploring online resources and tutorials. From Khan Academy to MIT OpenCourseWare, there are many free and accessible resources available for learning trigonometry and its applications.
