A) Sum-Difference Formula Tool
B) Trig Sum-Difference Calculator
C) Formulaic Summation Solver
D) Sum or Subtract Identity Evaluator

Answer 1

The sum or difference formula in trigonometry is used to find the sine, cosine, or tangent of the sum or difference of two angles.

Step-by-step explanation:

The sum or difference formula in trigonometry is used to find the sine, cosine, or tangent of the sum or difference of two angles. It is represented as:

sin(A + B) = sin(A)cos(B) + cos(A)sin(B)

sin(A - B) = sin(A)cos(B) - cos(A)sin(B)

To use the sum or difference formula with a calculator, you can either use a step-by-step approach or a function on a calculator like the TI-83, 83+, or 84. If using a calculator, you can input the values of the angles and use the appropriate formula to calculate the result.
