दिलेली माहिती:

, यात θ हा लघुकोन त्रिकोण आहे

वापरलेले सूत्र:

sin2θ + cos2θ = 1

tan θ =  , आणि 

cot θ = 

गणना:

 आणि  शोधण्यासाठी, आपल्याला  आवश्यक आहे:

sin2θ + cos2θ = 1

cos θ = 

⇒ 

⇒ 

⇒ 

⇒ 

आता,  यांची गणना करुन:

 ∴ tan θ  + cot θ चे मूल्य  हे आहे.

Shortcut Trick 

 = P/H, आपल्याला पायथागोरियन ट्रिपलेट माहित आहे  (8, 15, 17)

मग, पाया (B) = 15, म्हणून tan θ = P/B = 8/15, cot θ = 15/17

⇒ tan θ + cot θ 

⇒ 8/15 + 15/8 

⇒
