Verify the Pythagorean Identity 1 + cos^2(theta) = csc^2(theta)

1 + cot² t = csc² t
[tex]1+cot ^{2} t = \frac{1}{sin ^{2} t} \\ 1+ \frac{cos^{2}t }{sin^{2}t } = \frac{1}{sin ^{2} t} [/tex] / * sin² t
sin² t + cos² t = 1
1 = 1
We have confirmed the identity.

The verification for the Pythagorean identity 1 + cot²∅ = cosec²∅ will lead to sin²∅ + cos²∅ = 1

How to verify Pythagorean identity?

1 + cot²∅ = cosec²∅

Therefore,

cosec²∅ = 1 / sin²∅

cot²∅ = 1 / tan²∅ = cos²∅ / sin²∅

Hence,

1 + cos²∅ / sin²∅ = 1 / sin²∅

Therefore, multiply both sides by sin²∅

1(sin²∅) + (sin²∅) cos²∅ / sin²∅ = (sin²∅) 1 / sin²∅

sin²∅ + cos²∅ = 1
