What is Active Recall? Active recall is a study technique that goes beyond passive reading and memorization. Instead of merely reviewing notes or textbooks, or passive recall, simply remembering past material, active recall involves proactively retrieving information from memory while studying, which leads to more engaging and productive review sessions. This is often seen in…
Read articleIn order to find the integral of 1 x 2, we will use the power rule. In other words, we want to use $$ \dfrac d{dx}x^n = nx^{n-1}$$ to find $$\displaystyle\int \dfrac{1}{x^2}dx$$ At first, it is not clear how the two are related. Recall, however, that another name for the integral is antiderivative. In other…
Read articleIn the realm of calculus, certain integrals stand out for their frequent application and the elegant techniques required for their resolution. One such integral is \( \int \dfrac{1}{x^2+1} dx \), notable for its direct connection to the arctangent function, a fundamental element in trigonometric calculations. The process of integrating \( \dfrac{1}{x^2+1} \) showcases the synergy…
