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 !!
