Sinθ = opposite side / hypotenuse
cosθ = adjacent side / hypotenuse
tanθ = opposite side / adjacent side
cosecθ = hypotenuse / opposite side
secθ = hypotenuse / adjacent side
cotθ = adjacent side / opposite side
   sin (x) = cos (90-x)
   tan(x) = cot (90-x)
   sec(x) = cosec (90-x)
   cos(x) = sin(90-x)
   cot(x) = tan(90-x)
   cosec(x) = sec(90-x)
   sin∧ 2 A + cos ∧2 A = 1 
   sec∧ 2 A − tan∧ 2 A = 1
  cosec ∧2 A − cot ∧2 A = 1

Sin(sqr )x + cos(sqr)x = 1
tan(sqr)x + 1 = sec(sqr)x
cot(sqr)x + 1 = cosec(sqr)x
