if you multiply cosine and sine by 45 do you get the same answer?
Don't get confused, here.......cos(45) and sin(45) mean that we are finding the cosine and sine, respectively, of a 45 degree angle......they have the same value......we are not "multipying" the cosine and sine by 45.....!!!
Sine and Cosine of 45 are equal=1/sqrt(2), but
Sin^2 + Cos^2=1
