 4h comment Show that $y_1(x) = \int_c^x f(x-t) R(t) dt$ is a particular solution of $L(y) = R$ Try applying the Leibnitz rule. 1d comment the derivative of $\sin{x}$ is $\cos{x}$ Or even easier. put $h = z -x$ and let $\h \to 0$. 1d answered the derivative of $\sin{x}$ is $\cos{x}$ 1d revised the derivative of $\sin{x}$ is $\cos{x}$ address minor style issues 1d answered Calculate Effective rate of the loan 1d reviewed Reviewed Calculate Effective rate of the loan 1d comment Calculate Effective rate of the loan How often is interest compounded? 1d revised prove that if $S$ is a subspace of $V$,then $S ∩ S^\perp =\{0\}$ inserted latex 1d answered prove that if $S$ is a subspace of $V$,then $S ∩ S^\perp =\{0\}$ 2d comment Why is $\int\limits_{\gamma} \frac{1}{z-1} \neq 2\pi i$, $\gamma = \{z : \lvert z \rvert = 1\}$? There is a rather surly singularity at $z=1$; your curve passes right through that. All bets are off. 2d awarded Enlightened 2d awarded Nice Answer 2d reviewed Reviewed Probability Density Function with Cumulative Distribution & Standard Deviation 2d revised Probability Density Function with Cumulative Distribution & Standard Deviation reset in TeX and phrased in form of quesitons. 2d reviewed Reviewed How to handle dice probability? ie, how much more likely would 3 six sided dice give a higher sum than 3 four sided dice? 2d answered Pseudo-Cauchy sequence 2d comment Order Axioms: '<' or '$\leq$'? You should adopt a convention, explicity state it, and use it. 2d answered Confused by (cumulative) distribution function question… 2d comment Is there a mathematical symbol for “For every element”? For all x in A. You have it backwards. Apr14 answered R.V. X and Y have joint density $f(x, y) = e^{(-x-y)}$, find $P(X+Y\leq 1)$
