Maths - Trigonometry - Pythagoras theorem

The square on the hypotenuse is equal to the sum of the squares on the other two sides.

which gives:

a2 = b2 + c2

from which we can derive the following relationships between the trig functions:

sin2(θ) + cos2(θ) = 1

sin2(θ) = 1 + tan2(θ)

cosec2(θ) = 1 + cot2(θ)
