Where does the pythagorean identity sin^2 + cos^2=1 come from? How does it relate to right triangles?
Arada [10]
Consider a<span> right triangle with </span><span>hypotenuse of 1.
sin x means to divide the side in front of the angle by </span>hypotenuse<span>
cos x means to divide the side beside  the angle by hypotenuse
we know that a^2+b^2=c^2 now divide two sides by c^2
\frac{ a^{2} }{ c^{2} }+  \frac{ b^{2} }{ c^{2} }=1
c is 1 also a/c means sinx and b/c is cos x so
sin^2(x)+cos^2(x)=1
