the derivative of arctan
February 27th 2010, 12:11 PM #1
the derivative of arctan
Hi,
Hm, trying to get my head around this
the derivative of arctan is $\frac{1}{1+x^2}$
So the derivative of $arctan(0.5sinx)$ should be:
$\frac{cosx}{1+\frac{sin^2x}{4}}$ But that's apparently wrong.
Why?

Commutative Algebra
Extension and Contraction
Let $f: R\rightarrow S$ be a ring homomorphism. Let $I \triangleleft R, J \triangleleft S$. The extension $I^e$ of $I$ (with respect to $f$) is $\langle f(I) \rangle$. Then contraction $J^c$ of $J$
(with respect to $f$) is $f^{-1}(J)$, which is an ideal in $R$.

Integer numbers are whole numbers; they are always represented exactly (without a decimal point) in the computer word: -3, 0, 379, etc. For instance, 5 (decimal) is represented exactly by 101
