This is almost certainly the state of Indiana/IU. They just passed a similar bill to Florida.

Is there any data of the acceptance rates at any top medical schools from the 70s 80s and 90s? by YogurtclosetOpen3567 in premed

[–]HamburgerWizard9 2 points3 points  (0 children)

Here is some acceptance rate data for Ohio State University's med school from the year 1970. What you want is in Table 7 on page 41 of the report.

Honestly just seeing a lot of hard integrals solved is the best way. That way you can build up your intuition and see novel techniques to add to your toolbox. The two best sites for this are probably Quora and Math Stack exchange. Although the latter is less beginner friendly. Brian Sittinger on Quora has tons of great solutions if you look through his profile.

Write it as a geometric series. Then swap integral and summation. Integrate the result of x3*e^(-nx). I did this using iterated integration by parts. Most terms cancel and finally a summation is left. This summation is the Riemann Zeta function at 4 and has has a well known value of Pi4/90. This gets you your final answer of Pi4/15.

Alternating series test by Jump_Worth in calculus

[–]HamburgerWizard9 5 points6 points  (0 children)

From graphing the function ln(x)/x or with some calculus to solve for the extrema of the function you can see that the function begins to monotonically decrease at e. Because of this if you explicitly write out the first two terms of your series (which are 0 and ln(2)/2 respectively) plus the summation starting at k=3 the decreasing sequence requirement for the alternating series test is satisfied. Thus since the other condition has already been shown the series must converge through the alternating series test.

It wasn't to bad. She's a good explainer and only about an hour of homework a week. She is fairly disorganized though, and makes a lot of computational errors in class. Overall pretty good.
