Question

hey \[\int_{a}^{b}f(x)dx=\sum_{a}^{b}f(x)\]
do you guys think this correct
my prof wrote this and i corrected him that he missed \[\Delta x \] for the reimann sum. He said no that is correct? i don't got how is that correct

Answer 1

Reimann sum supposed to be \[\sum_{a}^{b}f(x)\Delta x\]

Answer 2

do you mean ?? ∫baf(x)dx=∑f(x)

Answer 3

sorry i ment... do you mean ∫baf(x)dx=∑f(x)
