Download Solution PDFयदि P cos α = 3 और 4 tan α = Q है, तो फिर P और Q के बीच क्या संबंध है, जो α से स्वतंत्र है?
Answer (Detailed Solution Below)
Detailed Solution
Download Solution PDFप्रयुक्त अवधारणा:
sec2 θ - tan2 θ = 1
गणना:
P cos α = 3
⇒ cos α = 3/P
⇒ sec α = P/3
4 tan α = Q
⇒ tan α = Q/4
दी गई अवधारणा से, हमें प्राप्त होता है
sec2 α - tan2 α = 1
⇒ P2/9 - Q2/16 = 1
∴ सही उत्तर विकल्प 3 है।
