 Apr21 accepted Negation of “Diane rode her bicycle 100 miles on Sunday” Apr18 asked Negation of “Diane rode her bicycle 100 miles on Sunday” Mar29 comment Integral of $\big((1+\cos(x))\sin(x)\big)^2$ Hint: $sin^{2}(x) = 1/2(1 - cos2x),cos^{2}(x) = 1/2(1 + cos2x)$ Mar29 comment How would I prove that the limit of $f(x) = 1/(x^2 - 1) = - 1$ as $x \to 0$ using the $\epsilon-\delta$ definition? Can you explain why f(x) in the title is different form the f(x) given in the text? Mar29 comment Integral of $\big((1+\cos(x))\sin(x)\big)^2$ What did you try?
