RE: [Bug or Suggestion]About HP Prime G1 New Beta Firmware
There are some other examples
(i)
Code:
normal((simplify(int(e^(sin(x))*(x*cos(x)^3-sin(x))/cos(x)^2,x))))
xcas gets：
Code:
(x*exp(tan(x/2)/(tan(x/2)^2+1))^2*tan(x/2)^2-x*exp(tan(x/2)/(tan(x/2)^2+1))^2+exp(tan(x/2)/(tan(x/2)^2+1))^2*tan(x/2)^2+exp(tan(x/2)/(tan(x/2)^2+1))^2)/(tan(x/2)^2-1)
Not the most simplified answer

(ii)
Code:
int((sqrt(1+x^2)+sqrt(1-x^2))/sqrt(1-x^4),x)
Code:
int((sqrt(1+x^2)+sqrt(1-x^2))/sqrt(-1+x^4),x)
