A problem in Dummit and Foote states:

Let k be a field and let k(x) be the field of rational functions in x with coefficients from k. Let$t\u03f5k\left(x\right)$ be the rational function $\frac{P\left(x\right)}{Q\left(x\right)}$ with relatively ' polynomials $P\left(x\right),Q\left(x\right)\u03f5k\left[x\right]$ , with $Q\left(x\right)\ne 0$ . Then k(x) is an extension of k(t) and to compute its degree it is necessary to compute the minimal polynomial with coefficients in k(t) satisfied by x.

By k(t), do they mean k adjoin t, i.e. the set of polynomials$k}_{0}+{k}_{1}\frac{P\left(x\right)}{Q\left(x\right)}+\dots +{k}_{n}{\left(\frac{P\left(x\right)}{Q\left(x\right)}\right)}^{n$ ? Or do they mean the set of rational functions in t, e.g. $\frac{\frac{P\left(x\right)}{Q\left(x\right)}+1}{2{\left(\frac{P\left(x\right)}{Q\left(x\right)}\right)}^{2}+3}$

How can you show that

$\frac{1}{1-\mathrm{cos}\theta -i\mathrm{sin}\theta}=\frac{1}{2}+\frac{i}{2}\times \mathrm{cot}\frac{\theta}{2}$ where $i=\sqrt{-1}?$

How to calculate $\mathrm{ln}(x)$

I know only to calculate $\mathrm{ln}()$ using a calculator, but is there a way to calculate it without calculator:for example: $\mathrm{ln}(4)=??$ as far as I know the only way to do so is to draw the graph of $ln$ but it primarily depends on values from calculator. So really is there some formula for $\mathrm{ln}()$ to calculate its exact value for a specific number?
