Jan 07, 2020 · Davneet Singh is a graduate from Indian Institute of Technology, Kanpur. He has been teaching from the past 9 years. He provides courses for Maths and Science at Teachoo. I saw a while ago in a book by Clifford Pickover, that whether $\displaystyle \sum_{n=1}^\infty\frac1{n^3\sin^2 n}$ converges is open. I would think that the question of its convergence is really... Oct 19, 2007 · Understand that PI (radians) is EQUIVALENT to 180 degrees, which means that PI/2 equals 90 degrees. I assume you know what a sine graph looks like. In that case, draw two sine graphs, one will use degrees, and the other will use pi. Compare the two and you will see that . sin 90 = sin (pi/2) = 1.
