Sin θ = 4/5
ఉపయోగించిన సూత్రం:
tan θ = P/B ; cot θ = B/P
పైథాగరియన్ సిద్ధాంతం ద్వారా:
⇒ H2 = P2 + B2
ఇక్కడ, P = లంబంగా ; B = ఆధారం ; H = కర్ణము
గణన:
Sin θ = 4/5 = P/H
పైథాగరియన్ సిద్ధాంతం ద్వారా :
⇒ H2 = P2 + B2
⇒ 52 = 42 + B2
⇒ B2 = 52 - 42
⇒ B = √(25 - 16) = √9
⇒ B = 3
tan θ - Cot θ
⇒ (P/B) - (B/P)
⇒ (4/3) - (3/4) = (16 - 9)/12
⇒ 7/12
∴ సరైన సమాధానం 7/12 .
