b sin θ= a
प्रयुक्त अवधारणा:
sin θ= लंब/कर्ण
sec θ= कर्ण/आधार
tan θ= लंब/आधार
गणना:
b sin θ=a
sin θ= a/b
इसलिए, लंब = a और कर्ण = b
(कर्ण)2 = (लंब)2 + (आधार)2
b2 = a2 + आधार2
आधार2 = b2 - a2
secθ = कर्ण/आधार = b/
tanθ = लंब/आधार = a/
इसलिए, secθ+ tanθ = b/
secθ + tanθ = (b+ a)/ (
∵ (b + a) = √(b + a) × √(b + a)
⇒ sec θ + tan θ =
sec θ+ tan θ=
