I've hot two assignments to do in pascal and i have no idea how to make it :(
i dont even have anything similar and i dont have time to search the web for answers now

I really need help and i need it as fast as it can be so please if anyone can help me with this i would really reallllyyy appreciate it
here it goes...

1) calculate by definition integral from a to b of (e^x)
( now i know that this integral in fact is area under curve and then you should have something like sum of these little squares that have side deltaX long...i need it step by step made...)

2) Write the algorithm for determining zero function
(also i need it step by step...first to define variable and then to define function etc...)

Thanx a lot
