HP 50g Calculate integral with and without EVAL
Hello everybody,
i would like to know why the EVAL key must be used for the calculation of the integral (https://www.integralcalculator.com/#exp...3&ubound=4): $$\int_{3}^{4} \left  x^24 \right dx$$If the EVAL key is not used (only key \>NUM), the 50g hangs up and the hourglass is displayed. The EVAL key is not required to calculate the integral (https://www.integralcalculator.com/#exp...2&ubound=2): $$\int_{2}^{2} \left  \sin(x) \right dx$$The result is displayed even if I only use \>NUM. Maybe someone has an explanation for me? Thank you and best regards Joerg
