 1h comment I like to know if there is approximated expression of something Doing a partial integration I get $$\int_0^x{t^9\over9!}e^{-t}\>dt=-{t^9\over 9!}e^{-t}\biggr|_0^x+\int_0^x{t^8 \over 8!}e^{-t}\>dt\ ,$$ giving a first term $-{x^9\over 9!}e^{-x}$. 1h revised Is there a Mobius (infinite) cylinder? added 134 characters in body 4h answered Is there a Mobius (infinite) cylinder? 5h answered Find area of shaded area in curve with range of values for $y$ 22h answered How to solve $2^x < x^2$ 1d answered How do I transpose an ellipse function to stretch the ellipse into curved space? 1d revised Evaluating $\int_{0}^{3} \sqrt{1+x}\: dx$ using Limit of a Sum approach added 179 characters in body 1d answered Prove this exp and log inequality? 1d answered Evaluating $\int_{0}^{3} \sqrt{1+x}\: dx$ using Limit of a Sum approach 1d revised Horizontal tangent line of a parametric curve added 4 characters in body 2d comment Probability with n dice @ByronSchmuland: Thank you for spotting the slip. 2d revised Probability with n dice deleted 1 character in body 2d revised Water filling problem in Blocks - Algebra Question added 32 characters in body 2d answered Probability with n dice 2d answered Horizontal tangent line of a parametric curve 2d comment A piecewise regular simple closed curve bisects the area of the unit sphere if and only if it has total geodesic curvature 0 Take a look at the Gauss-Bonnet theorem. 2d answered Having trouble deriving the symbols used in a quadratric approximation problem. 2d revised A nice and hard colouring problem deleted 7 characters in body 2d revised Similar triangle proof in parallelogram added 59 characters in body 2d answered A nice and hard colouring problem
