-This is the changes log for the fontinst font installation package.
+This is the old changes log for the fontinst font installation package.
+As of v1.9, changes in the core are recorded using the \changes
+mechanism of the doc package, and appear as a section in the typeset form
+of the source (fisource.dvi). Changes to supporting files are typically
+recorded in each file, at the end.
Feb 4 1993, v0.01: Created the file, wrote an afm and enc parser,
started on a vpl writer.

+% The predecessor of this file is v\,1.09 of \texttt{trig.dtx}, the
+% source for the \package{trig} package in the standard \LaTeX\
+% ``graphics'' bundle. It has been inlined into the \package{fontinst}
+% source mainly because archive maintainers never seem to tire of
+% questioning the need to provide \texttt{trig.sty} with
+% \package{fontinst}.

+% \section{Trigonometrical functions}
+%
+% These macros implement the trigonometric functions, sin, cos and tan.
+% In each case two commands are defined. For instance the command
+% |\CalculateSin{33}| may be isued at some point, and then anywhere
+% later in the document, the command |\UseSin{33}| will return the
+% decimal expansion of $\sin(33^\circ)$.
+%
+% The arguments to these macros do not have to be whole numbers,
+% although in the case of whole numbers, \LaTeX\ or plain \TeX\ counters
+% may be used. In \TeX{}Book syntax, arguments must be of type:
+% \meta{optional signs}\meta{factor}
+%
+% Some other examples are:\\
+% |\CalculateSin{22.5}|, |\UseTan{\int{myvar}}|,
+% |\UseCos{\count@}|.
+%
+% Note that unlike the psfig macros, these save all previously
+% computed values. This could easily be changed, but I thought that in
+% many applications one would want many instances of the
+% same value. (eg rotating all the headings of a table by the
+% \emph{same} amount).
+%
+% I don't really like this need to pre-calculate the values, I
+% originally implemented |\UseSin| so that it automatically calculated
+% the value if it was not pre-stored. This worked fine in testing, until
+% I remembered why one needs these values. You want to be able to say
+% |\dimen2=\UseSin{30}\dimen0|. Which means that |\UseSin| must
+% \emph{expand} to a \meta{factor}.

+% The approximation to $\sin$. I experimented with various
+% approximations based on Tchebicheff polynomials, and also some
+% approximations from a SIAM handbook `Computer Approximations' However
+% the standard Taylor series seems sufficiently accurate, and used by
+% far the fewest \TeX\ tokens, as the coefficients are all rational.
+% \begin{eqnarray*}
+% \sin(x)& \simeq&
+% x - (1/3!)x^3 + (1/5!)x^5 - (1/7!)x^7 + (1/9!)x^9\\
+% &\simeq&
+% \frac{((((7!/9!x^2-7!/7!)x^2+7!/5!)x^2 +7!/3!)x^2+7!/1!)x}{7!}\\
+% &=& \frac{ ((((1/72x^2-1)x^2+42)x^2 +840)x^2+5040)x }{5040}
+% \end{eqnarray*}
+% The nested form used above reduces the number of operations required.
+% In order to further reduce the number of operations, and more
+% importantly reduce the number of tokens used, we can precompute the
+% coefficients. Note that we cannot use $9!$ as the denominator as
+% this would cause overflow of \TeX's arithmetic.

+% \begin{macro}{\TG@rem@pt}
+% The standard trick of getting a real number out of a \meta{dimen}.
+% This gives a maximum accuracy of approx.\ 5 decimal places, which
+% should be sufficient. It puts a space after the number, perhaps it
+% shouldn't.
+% \changes{1.930}{2005/02/06}{Using \cs{lose_measure}. (LH)}

+% |#1|.

+% \end{macrocode}
+% |\dimen@| now contains the angle in radians, as a \meta{dimen}.
+% We need to remove the units, so store the same value as a
+% \meta{factor} in |\@tempa|.
+% \begin{macrocode}
+ \edef\@tempa{\TG@rem@pt\dimen@}
+% \end{macrocode}
+% Now put $x^2$ in |\dimen@| and |\@tempb|.

+% \begin{macro}{\CalculateSin}
+% If this angle has already been computed, do nothing, else store

+% \begin{macro}{\CalculateTan}
+% Originally I coded the Taylor series for tan, but it seems to
+% be more accurate to just take the ratio of the sine and cosine.
+% This is accurate to 4 decimal places for angles up to
+% $50^\circ$, after that the accuracy tails off, giving
+% $57.47894$ instead of $57.2900$ for $89^\circ$.

+% Computed tangents are stored in control sequences with names of the
