One of the papers that cites Tai's: http://www.lexjansen.com/wuss/2004/posters/c_post_the_sas_calculations_.pdf It includes a formula Tai 'invented' (quotes in the paper) and acknowledges that it is the trapezoid rule. I can't find Tai's full paper of course, but this article shows that Tai frighteningly might have been serious about his discovery, but also that at least some MDs took calculus.
