In any triangle is sinA+sinB+sinC=332 always Well, I came with an interesting proof. But I just want to verify it Applied at function y=sinx We have, sin(A+B+C2)sinA+sinB+sinC3 From here we will get sinA+sinB+sinC332 Also by A.M. G.M. in an acute angled triangle sinA+sinB+sinC3sinAsinBsinC3 sinA+sinB+sinC3(sinAsinBsinC3) sinA+sinB+sinC3(32)=332>2 and from this I get sinA+sinB+sinC332

I have an impulse train given by
1R+1+k=1Rcos(2kπxR+1)R+1
It seems obvious to me that, for x=0, the function returns 1. This is because cos(0)=1, and we therefore end up with 1R+1+RR+1=R+1R+1=1
However indeterminate result at x=0. Usually this means there is a division by 0 somewhere. But I can't see any reason for this function to produce an indeterminate result.
