H ave you ever wondered why does this spooky... no not spooky rather a simple and pretty trigonometry identity  "sin^2(θ) + cos^2( θ) = 1"  came into existence    ? You may probably remember this identity from your high school mathematics. But if you don't then there is no problem. There is no need for you to sweat over it. Just simply google this and you will find about it. Today we will see the story of this identity. But before diving into the story of sin^2( θ) + cos^2( θ) = 1 , we need to travel back into time to ancient Ionian Greek so that we can meet Mr. Pythagoras aka Pythagoras of Samos and get to know about his famous Pythagoras Theorem . So, ladies and gentleman tighten your seat belt as our time machine is going back into time. Close your eyes and enjoy the journey. Three...Two...One... Cool we have finally reached to our destination. Mr. Pythagoras is telling his theorem so read carefully else you may cube a side.  Great! We got to know about Pythagoras Theo
