5) For each of the integrals in problems a c below, first sketch the corresponding area, and then approximate the area using the right and left endpoint approximations and the Trapezoid Rule, all with n = 4 . From your sketch alone determine if each approximation is an overestimate, an underestimate, or if there is not enough information to tell. Finally determine the value of n for which the Simpson Rule would approximate the...
this is the correct answer. please show the work for this.
also, please plug your work into the calculator to make sure it was
right. i have posted this before and was given incorrect
work.
Referring to the image below, if Force A = {3.0} N, Force B = {27.0} N, P = {115.0} degreesas measured from the +X-axis, Ra= (3.6} cm, and Rb={11.8} cm, what will Force C have to be if it is to keep the wheel in...
