RE: [Bug or Suggestion]About HP Prime G1 New Beta Firmware
In the process of using, I have encountered more troublesome indefinite points.
(i) Code: ∫(e^atan(x)/(sqrt(x^2+1))/(1+x^2),x) Code: subst(∫(e^atan(x)/(sqrt(x^2+1))/(1+x^2),x),x=tan(t)) But the new firmware can't be solved (ii) Code: int(1/sqrt(x^3x),x) Code: ∫(1/(1+x^4)^(5/4)) (iii) Code: ∫(x*e^x/(sqrt(e^x1)),x) Code: subst(∫((e^x*sqrt(e^x1)*x)/(e^x1),x),equal(x,ln(t^2+1))) Code: 2*t*ln(t^2+1)*sign(t)4*t*sign(t)+4*atan(t)*sign(t) study hard, improve every day
