Use our free Cosine Subtraction Calculator to quickly determine the cosine of the difference between two angles. This online tool simplifies complex trigonometric calculations using the formula cos(A-B) = cos(A)cos(B) + sin(A)sin(B). Perfect for students, engineers, and anyone needing accurate trigonometric results.
Formula:
The Cosine Subtraction Formula is given by:
cos(A - B) = cos(A)cos(B) + sin(A)sin(B)
Where:
- A = The first angle
- B = The second angle
