tanθ =
sinθ/cosθ
1 of 23
sin^2 θ + cos^2 θ =
1
2 of 23
cosecθ =
1/sinθ
3 of 23
secθ =
1/cosθ
4 of 23
cotθ =
1/tanθ
5 of 23
1/tanθ =
cosθ/sinθ ∴ cotθ = 1/tanθ = cosθ/sinθ

9 of 23
Sin(A-B) =
SinACosB - CosASinB
10 of 23
Cos(A+B) =
CosACosB - SinASinB
11 of 23
Cos(A-B) =
CosACosB + SinASinB
12 of 23
Tan(A+B) =
(TanA + TanB)/(1 - TanATanB)
13 of 23
Tan(A-B) =
(TanA - TanB)/(1 + TanATanB)
14 of 23
Sin2A ≡

2Sin((P+Q)/2)Cos((P-Q)/2)
20 of 23
SinP - SinQ ≡
2Cos((P+Q)/2)Sin((P-Q)/2)
21 of 23
CosP + CosQ ≡
2Cos((P+Q)/2)Cos((P-Q)/2)
22 of 23
