Reimann Sum... I got it wrong twice... Please help and provide step by step clear explaination. I'd appreciate it.
AnnyKZ [126]
Formula for Riemann Sum is:
\frac{b-a}{n} \sum_{i=1}^n f(a + i \frac{b-a}{n})
interval is [1,3] so a = 1, b = 3
f(x) = 3x , sub into Riemann sum

\frac{2}{n} \sum_{i=1}^n 3(1 + \frac{2i}{n})

Continue by simplifying using properties of summations.
= \frac{2}{n}\sum_{i=1}^n 3 +  \frac{2}{n}\sum_{i=1}^n \frac{6i}{n} \\  \\ = \frac{6}{n}\sum_{i=1}^n 1 +  \frac{12}{n^2}\sum_{i=1}^n i \\  \\ =\frac{6}{n} (n) + \frac{12}{n^2}(\frac{n(n+1)}{2}) \\  \\ =6+\frac{6}{n}(n+1) \\  \\ =12 + \frac{6}{n}

Now you have an expression for the summation in terms of 'n'.

Next, take the limit as n-> infinity.
The limit of \frac{6}{n} goes to 0, therefore the limit of the summation is 12.

The area under the curve from [1,3] is equal to limit of summation which is 12.
