Additional Information :

  • sin² θ + cos² θ = 1
  • sin² θ = 1 - cos²θ
  • sec²θ = 1 + tan²θ
  • cot²θ = cosec²θ - 1

★ Reciprocal identities :-

  • [tex]\red{\boxed{cos θ = \dfrac{1}{ sec θ}}}[/tex]
  • [tex]\red{\boxed{sec θ = \dfrac{1}{cos θ}}}[/tex]
  • [tex]\red{\boxed{tan θ = \dfrac{1}{ cot θ}}}[/tex]
