Answer 2

Hey !!!

Nice question ...

Sin²¢ + cos²¢ = 1 How ?

so... let a right triangle ABC in which AB is "p" perpendicular BC is "b" base and AC is" h" heipotenous..

now. . As we know that

h² = P² + b² [ by using Pythagoras theorem]-----1)

Now we know that ..

sin¢ =P/h

cos¢ =b/h

so..

sin²¢ + cos²¢

=> (p/h )²+ (b/h)²

=> p²+b²
---------------
h²

=> h² /h² {from equation 1>}

=> 1 Answer ...

hope it helps you !!!
