RE: sin(x)^2+cos(x)^2 = 1 on different calcs
I dunno how its relevant: on my CASIO fx-991ES SUM(SIN(X)^2+COS(X)^2-1,0,90) gives 0, SUM(SIN(X)^2+COS(X)^2,0,90)-91 also 0, SUM(SIN(X)^2,0,90)+SUM(COS(X)^2,0,90)-91 same (0). After then I used integration and the result is also zero! Wow! My CASIO is perfect.
