Maximum value of Sin@ is 1 ie when @=pi/4
If A=B=C=pi/4 then the value will be 1+1+1=3
Hence max value of SinA+SinB+SinC=3

any trigonometric ratio can be at most equal to 1, so if the value is maximum, all three ratios can be equal to one and thus summing up2 1!hope my word has reached u!

Generally it is 3 because max value of each of the 3 ratios is 1. But in a triangle, it is 3 3/2.
