Detailed Solution
Download Solution PDFகொடுக்கப்பட்டது:
sec θ + tan θ = 5
பயன்படுத்தப்பட்ட கருத்து:
sec θ + tan θ = y என்றால்
பின்னர் sec θ - tan θ = 1/y
கணக்கீடு:
sec θ + tan θ = 5 ----- (1)
பிறகு,
sec θ - tan θ = 1/5 ------- (2)
சமன்பாடு (1) மற்றும் (2) ஐக் கழித்தல்.
⇒ (sec θ + tan θ) - (sec θ - tan θ) = (5 - 1/5)
⇒ sec θ + tan θ - sec θ + tan θ = 24/5
⇒ 2 x tan θ = 24/5
⇒ tan θ = 12/5
∴ சரியான பதில் 12/5.
