Detailed Solution
Download Solution PDFदिलेल्याप्रमाणे:
{(3Sinθ – Cosθ)/(Cosθ + Sinθ)} = 1
गणना:
आपल्याकडे त्रिकोणमितीय समीकरण आहे
{(3Sinθ – Cosθ)/(Cosθ + Sinθ)} = 1
अंश आणि भाजक यांना sin θ ने भागल्यास, आपल्याला मिळते
⇒ [{(3sinθ – cosθ)/Sinθ}/{(cosθ + sinθ)/sinθ}] = 1
⇒ {(3 – cotθ)/(cotθ + 1)} = 1
⇒ 3 – cotθ = 1 + cotθ
⇒ 2cotθ = 2
cotθ = 1
मूल्य 1 आहे.
