Probability Introduction :

In this math-formula-sheet-angles let us provide the sum and difference of the trigonometric ratios Sin, Cos, Tan, Cot angles.

I. Sum and difference angles of Sine, Cos, Tan, Cot

 1) Sin(A+B) = Sin(A)Cos(B) + Cos(A)Sin(B)

 2) Sin(A-B) = Sin(A)Cos(B) - Cos(A)Sin(B)

 3)Cos(A+B) = Cos(A)Cos(B) - Sin(A)Sin(B)

 4) Cos(A-B) = Cos(A)Cos(B) + Sin(A)Sin(B)

 5) Tan(A+B) = \(\frac{Tan(A) + Tan(B)}{1 - Tan(A)Tan(B)}\)

 6) Tan(A-B) = \(\frac{Tan(A) - Tan(B)}{1 + Tan(A)Tan(B)}\)

 7)Cot(A+B)=\(\frac{Cot(A)Cot(B)-1}{Cot(B)+Cot(A)}\)

 8)Cot(A-B)=\(\frac{Cot(A)Cot(B)+1}{Cot(B)-Cot(A)}\)
