[Bug or Suggestion]About HP Prime G1 New Beta Firmware

[yangyongkang]

I downloaded the latest HP Prime RC 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:
