Pythagorean Identities {Part 1 of 3}

Pythagorean Identity #1

The example below depicts how this identity came about. Using an angle, in reference to the Unit Circle, you see how I prove that sin^2(x) + cos^2(x) is ALWAYS going to equal to one.

Pythagorean Identity #2

This is derived in reference to sin^2(

𝞡

) + cos^2(

𝞡

) = 1 and dividing it by cos^2𝞡

Pythagorean Identity #3

This pythagorean identity is also derived in  reference to sin^2(

𝞡

) + cos^2(

𝞡

) = 1 and, but instead you are dividing it by sin^2𝞡
