Mar16 asked Notation for multiple of a number? Oct11 accepted Derivative of square of derivative? Oct10 comment Derivative of square of derivative? Thanks for the answer! Oct10 comment Derivative of square of derivative? The first one: $$\frac{d}{dy}\bigg(\frac{dy}{dx}\bigg)^2$$ Oct10 awarded Commentator Oct10 comment Derivative of square of derivative? This is okay, but I wanted to get is $\frac{d}{dy}z$ not $\frac{d}{dx}z$ Oct10 comment Derivative of square of derivative? I have tried it, but when I try to integrate it can't seem to get the original expression. Oct10 asked Derivative of square of derivative? Aug5 accepted Help on differential equation $y''-2\sin y'+3y=\cos x$ Jul23 comment Help on differential equation $y''-2\sin y'+3y=\cos x$ Yes, it is $-2\sin y'$ Jul23 asked Help on differential equation $y''-2\sin y'+3y=\cos x$ Jul20 revised Hypergeometric series \sum instead of Sigma Jul20 suggested approved edit on Hypergeometric series Jul17 accepted Laplace transform of $\int_1^\infty\frac{\cos t}{t}dt$ Jul17 comment Laplace transform of $\int_1^\infty\frac{\cos t}{t}dt$ ok, thanks. I just hope I don't have to solve the integral Jul17 awarded Editor
