[Bug or Suggestion]About HP Prime G1 New Beta Firmware
This is the information of my calculator
Code:
HP Prime: "HP Prime Graphing Calculator Software Version: 2.1.14341 (2019 11 20) BETA Hardware Version: A CAS Version: 1.5.0 Serial Number: 4CY3450CZZ Operating System: V0.050.640 © 2019 HP Development Company, L.P. "
The following are the problems I encountered during use：

(i)
Code:
plotfunc(x^ln(x))
Then click Show, the calculator restarts

(ii)
Code:
int(atan(x)/(x^2*(1+x^2)),x)
Hp prime didn't figure it out, this is the result of Wolfram Alpha

(iii)
Code:
simplify((1/sin((π/18)))-(sqrt(3)/cos((π/18))))
Hp prime calculation result：
Code:
(-√3*tan(2/9*π)^4+√3-2*tan(2/9*π)^3-2*tan(2/9*π))/(2*tan(2/9*π)^3-2*tan(2/9*π))
Actually
Code:
evalf((1/sin((π/18)))-(sqrt(3)/cos((π/18))))
Hp prime calculation result：
Code:
4

study hard, improve every day
