    Pythagoras' Theorem says that for a right-angled triangle, the square of the long side equals the sum of the squares of the other two sides:
    x^2 + y^2 = 1^2
    But 1^2 is just 1, so: x^2 + y^2 = 1 -- the equation of the unit circle

      Hey I have a question ,
      Just take a look at this simple equation I came up with when I was bored,
      20 = 20
      20 can also be written as 36 - 16 & 16 + 4
      So rewriting it as ,
      36 - 16 = 16 + 4
      Now is we take square roots on both sides we get ,
      6 - 4 = 4 + 2
      Which gives us
      2 = 6 😬😬😬
      Nothing wrong with any of the calculations
      Then how did we get to this 😲🤔🤔

    FINALLY! OMG! FINALLY! I FINALLY know where sin theatre squared + cos theatre squared = 1 comes from! Thank you SO MUCH! SO MUCH INSIGHT! Omg...I did my year 12 final maths exam not knowing where it comes from and still passed the test. Truly passing an exam is not equivalent to understanding Maths. Thank you so much OMG.
