I could use some help with the following calculus problems:

Find the indefinite integral. Remember to include a \"+ C" if appropriate. Include a multiplication sign between functions. For example, if * at .. feidt= II@ Find the indefinite integral. Remember to include a \"+ C" if appropriate. Enclose arguments of functions in parentheses. For example, sin (23). L Mm _W) -m 1 m+6 (a) Estimate the area under the graph of the function 3" (ac) = from :1: = 0 to :1: = 5 using a Fliemann sum with n = 10 subintervals and right endpoints. Round your answer to four decimal places. area = Number (b) Estimate the area under the graph of the function f (to) = 1 3+6 from a: = 0 to a: = 5 using a Riemann sum with n = 10 subintervals and left endpoints. Round your answer to four decimal places. area = Number Estimate the area under the graph of the function f (m) = x/m + 3 from a; = 2 to a: = 4 using a Riemann sum with n = 10 subintervals and midpoints. Round your answer to four decimal places. area = Number
