Integral calculus question below! :)
Recall that a differentiable function F(x) is said to be increasing at a point a F'(a)>=0. Show that this function is always increasing: \[\int\limits_{0}^{e^x}e^{e^{t}}\]
i can tell you this i have trouble with these types of problems sorry i couldnt help ;-;
\[\Large\rm F(x)=\int\limits\limits_{0}^{e^x}e^{e^{\color{orangered}{t}}}dt\]By the Fundamental Theorem of Calculus, Part 1, we can calculate our derivative,\[\Large\rm F'(x)=e^{e^{\color{orangered}{e^x}}}(e^x)'\]Fundamental Theorem + Chain rule applied above.\[\large\rm F'(x)=e^{e^{e^x}+x}\]So you have an exponential function... which is never negative, ya? :)
Ok lemme know if you confused when you get back on salt lady :)
Hahaha had a total brain fart. Thanks! @zepdrix
e^x = t and solve
