வைக் கண்டுபிடிக்க மற்றும், நமக்குத் தேவையானது:

sin2θ + cos2θ = 1

cos θ = 

⇒ 

⇒ 

⇒ 

⇒ 

இப்போது, கணக்கிட்டால்:

  ∴ tan θ  + cot θ  இன் மதிப்பு .

 Shortcut Trick

  = P/H, பித்தகோரியன் மும்மை என்பது  (8, 15, 17) என்று நமக்குத் தெரியும்.

பின்னர், அடிப்பக்கம் (B) = 15, எனவே tan θ = P/B = 8/15, cot θ = 15/17

⇒ tan θ + cot θ
