Can someone do a calculation on a TI Inspire CAS?

For values of x around \(\pi\), \(sin(x) \approx \pi-x\)

The value of \(\pi\) is closer to 3.14159265358979, and \(3.14159265358979-3.141592654=-4.1021\times10^{-10}\) so I'd say this machine is right on the money.

The inaccuracy here isn't in the calculator, it's in the assumed value of \(\pi\).

I was not assuming anything...I was asking for the SIN of a specific input, and the HPs give a much higher accuracy than the TIZs...The HP 28, 42S, 48 series 50G and prime etc give the answer correct to 12 digits, the TI is not even close.
