Download Solution PDFఇచ్చినది:
{(3Sinθ - Cosθ)/(Cosθ + Sinθ)} = 1
గణన:
మనకు త్రికోణమితి సమీకరణం ఉంది
{(3Sinθ - Cosθ)/(Cosθ + Sinθ)} = 1
లవము మరియు హారంను sin θతో భాగిస్తే, మనకు ఇలా లభిస్తుంది
⇒ [{(3sinθ - cosθ)/Sinθ}/{(cosθ + sinθ)/sinθ}] = 1
⇒ {(3 - cotθ)/(cotθ + 1)} = 1
⇒ 3 - cotθ = 1 + cotθ
⇒ 2cotθ = 2
cotθ = 1
విలువ 1.
