Calculator in Check Your Understanding sections
Can you please add a Show Calculator button like there is on quizzes and unit tests in the appropriate Check Your Understanding sections in articles? The Check Your Understanding questions often ask the exact same questions that appear on the quizzes and unit tests, but there's never a show calculator button in those sections like there is during the quizzes and tests. Without the calculator available in those articles, it places an undue strain on those with more difficult access to personal calculators. As an example, the last check your understanding question here:
asks you to divide the opposite side length by the adjacent side length, two decimal values. While that's unnecessarily complex to demonstrate the understanding of the topic, it's fairly easily doable, but once you start getting into the Check Your Understanding sections further into precalculus and calculus, the questions start requiring the use of a graphic/scientific calculator that Khan Academy provides for the exact same problems in the quizzes/tests but does not provide for the Check Your Understanding questions in the articles preceding them.
