Answer (Detailed Solution Below)
Detailed Solution
Download Solution PDFअवधारणा:
sin2 θ + cos2 θ = 1
गणना:
7 sinθ + 24 cosθ = 25
दोनों तरफ से 25 को विभाजित करके, हम प्राप्त करते हैं
हम जानते हैं कि,
sin2 θ + cos2 θ = 1
sin θ.sin θ + cos θ.cos θ = 1 ....(ii)
समीकरण (i) और (ii) तुलना करने पर
sin θ =
cos θ =
अब, (sinθ + cosθ)
=
=
