The word trigonometry is derived from the Greek words tri = three, gon = sides and metron = measure.

right angle
  • sin θ = A/H
  • cos θ = O/H
  • tan θ = A/O
  • cosec θ = H/A
  • sec θ = H/O
  • cot θ = O/A
Reciprocal Identities
sin θ =
1csc θ
csc θ =
1sin θ
cos θ =
1sec θ
sec θ =
1cos θ
tan θ =
1cot θ
cot θ =
1tan θ
Quotient Identities
tan θ =
sin θcos θ
cot θ =
cos θsin θ
Pythagorean Identities
Sin2θ + Cos2θ = 1
Sec2θ - Tan2θ = 1
Cosec2θ - Cot2θ = 1
