Question

Calculate the Left Riemann sum for the function over the given interval using the given values of n
f(x)=6x-2 over (0,2) n=4

Answer 1

Do you know how to start?

Answer 2

@luigi0210 no i don't

Answer 3

\[\sum_{i=0}^{4}(6x_{i}-2) \Delta (x) \]
where x(i) is (0+i*(delta(x))
and delta(x) is (0+2)/4=0.5
and so the summation becomes
\[0.5\sum_{i=0}^{4}3i-2\]
which I hope it is easy for you to compute.

Answer 4

I don't think that's the correct set-up
