  📊 त्रिकोणमिति : महत्वपूर्ण सूत्र 📊


🍎 योग सूत्र

➭ Sin(A+B) = SinACosB+CosASinB

➭ Sin(A-B) = SinACosB-CosASinB

➭ Cos(A+B) = CosACosB-SinASinB

➭ Cos(A-B) = CosACosB+SinASinB


🍏 अन्तर सूत्र

➭ tan(A+B) = tanA+tanB/1-tanAtanB

➭ tan(A-B) = tanA-tanB/1+tanAtanB


🍎 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

➛ 2SinACosB = Sin(A+B)+Sin(A-B)

➛ 2CosASinB = Sin(A+B)-Sin(A-B)

➛ 2CosACosB = Cos(A+B)+Cos(A-B)

➛ 2SinASinB = Cos(A-B)-Cos(A+B)


🍎 द्विक कोण सूत्र 

➛ Sin2A = 2SinACosA

➛ 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-B) = Sin²A-Sin²B 

                                 = Cos²B-Cos²A

➛ Cos(A+B)Cos(A-B) = Cos²A-Sin²B = Cos²B-Sin²A


🍎 त्रिक कोण सूत्र

➛ Sin3A = 3SinA-4Sin³A

➛ Cos3A = 4Cos³A-3CosA

➛ tan3A = 3tanA-tan³A/1-3tan²A


🍏 महत्वपूर्ण सर्वसमिकाएं

➛ Sin²θ+Cos²θ = 1

➭ Sin²θ = 1-Cos²θ 

➭ Cos²θ = 1-Sin²θ

➛ 1+tan²θ = Sec²θ

➭ Sec²θ-tan²θ = 1

➭ tan²θ = Sec²θ-1

➛ 1+Cot²θ = Cosec²θ

➭ Cosec²θ-Cot²θ = 1

➭ Cot²θ = Cosec²θ-1

Utkarsh Dwivedi AIR-5 PSIR Notes, Strategy and ANSWER COPIES

Utkarsh Dwivedi IAS   air-5 UPsc cse 2021 PSIR STRATEGY, NOTES AND MY ANSWER COPIES If there is one factor that has helped me achieve a single digit rank in CSE, it is my optional. I have scored 168 in paper 1 and 146 in paper 2, making it 314 in total. I have still not come across somebody with a score more than this and hence a comfortable claim can be made that this is one of the highest score this year. In this blog, I would mention what helped me achieve this score.  I DID NOT refer to any other source than Shubhra Ma'am's notes. There are two reasons to it.  Firstly, since I had reached the interview stage in all my three attempts, I never had the luxury of time to refer to any book.  Secondly, I believe Ma'am's notes are more than enough to form the core aspect of the subject's preparation. I did value addition from multiple sources so as to get an edge in my answers: I referred to copies of toppers of the respective tests that I attempted during my mains ...
