त्रिकोणमिति सूत्र

By -

समकोण त्रिभुज का नियम(Right Angle tringle's Rule):-


  • (कर्ण)2=(लम्ब)2+(आधार)2
  • (लम्ब)2=(कर्ण)2-(आधार)2
  • (आधार)2=(कर्ण)2-(लम्ब)2

त्रिकोणमिति अनुपात(Trigonometric Ratio):-


  • sinθ= लम्ब /कर्ण
  • cosθ= आधार /कर्ण
  • tanθ= लम्ब /आधार
  • cotθ= आधार /लम्ब
  • secθ= कर्ण /आधार
  • cosecθ= कर्ण /लम्ब

नोट:- आप इस TRICK के द्वारा भी इसे याद रख सकते हैं।

त्रिकोणमिति सम्बन्ध(Trigonometric Relation):-



  • sinθ.cosecθ=1
  • cosθ.secθ=1
  • tanθ.cotθ=1
  • tanθ=sinθ/cosθ

त्रिकोणमिति सारणी(Trigonometric Chart):-


कुछ महत्वपूर्ण सूत्र (Some Important Formulas):-

  • Sin2θ +cos2θ=1
  • 1+tan2θ=sec2θ
  • 1+cot2θ=cosec2θ
  • sin(A+B)=sinA.cosB+cosA.sinB
  • sin(A-B)=sinA.cosB-cosA.sinB
  • cos(A+B)=cosA.cosB-sinA.sinB
  • cos(A-B)=cosA.cosB+sinA.sinB
  • tan(A+B)=(tanA+tanB)/(1-tanA.tanB)
  • tan(A-B)=(tanA-tanB)/(1+tanA.tanB)
  • sin2A=2sinA.cosA
  • cos2A=cos2A-sin2A=2cos2A-1=1-2sin2A
  • tan2A=2tanA/(1-tan2A)
