Question 10 1 pts Let f(x) =2x* over the interval [1 , 2] . Find a formula for the Riemann sum obtained by dividing the interval 1 , 2] into n equal sub-intervals and using the right endpoint for each Ck . Then, take a limit of these sums as noo to calculate the true area under the graph of f over [1 , 2] . Show and explain your work. Upload Choose a FileQuestion 8 1 pts Let f(x) =sina+1 on -7, 7].
