I need help with these please.

Find the indefinite integral. Remember to include a "+ C" if appropriate. Enclose arguments of functions in parentheses. For example, sin (2ac). 1 all - 6 sin (x) dx =1 (a) Estimate the area under the graph of the function f(:r:) : from :r: : 0 to :I: : 2 using a Riemann ml4 sum with n : 10 subintervals and right endpoints. Round your answer to four decimal places. area : Number 1 (b) Estimate the area under the graph of the function f(:I:) : from :1: : 0 to a: : 2 using a Riemann a3+4 sum with n : 10 subintervals and left endpoints. Round your answer to four decimal places. area : Number
