💠 *योग सूत्र* 😀

🔹 Sin(A + B) = SinACosB +
CosASinB
🔺Sin(A - B) = SinACosB -
CosASinB
🔹Cos(A + B) = CosACosB -
SinASinB
🔺Cos(A - B) = CosA.CosB +
SinA.SinB

💠 *अन्तर सूत्र* 😀

🔹tan(A + B) = tanA + tanB/1 -
tanA.tanB
🔺tan(A - B) = tanA - tanB/1 +
tanA.tanB

💠 *C - D सूत्र* 😀

🔹SinC + SinD = 2Sin(C + D/2)
Cos(C - D/2)
🔺SinC - SinD = 2Cos(C + D/2)
Sin(C - D/2)
🔹CosC + CosD = 2Cos(C + D/
2) Cos(C - D/2)
🔺CosC - CosD = 2Sin(C + D/2)
Sin(D - C/2)
🔹CosC - CosD = - 2Sin(C + D/
2) Sin(C - D/2)

💠 *रूपांतरण सूत्र 😀*

🔹2SinA.CosB = Sin(A + B) +
Sin(A-B)
🔺2CosA.SinB = Sin(A + B) -
Sin(A - B)
🔹2CosA.CosB = Cos(A + B) +
Cos(A-B)
🔺2SinA.SinB = Cos(A - B) -
Cos(A + B)

💠 *द्विक कोण सूत्र* 😀

🔹Sin2A = 2SinA.CosA
🔺Cos2A = Cos²A - Sin²A =
2Cos² - 1 = 1 - 2Sin²A
🔹tan2A = 2tanA/1 - tan²A
🔺Sin2A = 2tanA/1 + tan²A
🔹Cos2A = 1 - tan²A/1 + tan²A

💠 *विशिष्ट सूत्र* 😀

🔹Sin(A + B) = Sin A . Cos B +
Cos A . Sin B
🔺Sin(A - B) = Sin A . Cos B −
Cos A . Sin B
🔹Cos (A + B) = Cos A . Cos B −
Sin A . Sin B
🔺Cos ( A - B ) = Cos A . Cos B
+ Sin A . Sin B
