✔ स्पष्टीकरण :-
✔ दत्त :-
( यहा पर थीटा = A है | )
- SinA + Sin²A = 1
✔ सिद्ध करना है :-
- Cos²A + Cos^{4}A = 1
✔ सिद्धता :-
दिया है : SinA + Sin²A = 1
➡ SinA = 1 - Sin²A ___________(1)
[ °.° Sin²A + Cos²A = 1 ]
➡ Cos²A = 1 - Sin²A _________(2)
समी. (1) & (2) से ,
➡ SinA = Cos²A
दिया है : SinA + Sin²A = 1
➡ (Cos²A) + (Cos²A)² = 1
➡ Cos²A + Cos^{4}A = 1
सिद्ध हो गया !!
