Simon Budig	38468bfbd0	3d-function-8.tex: convert argument of sin() to degrees. ... tikz apparently expectes the argument to sin() in degrees. This is in strong contrast to the usual conventions in math, where the argument is expected in radians. With this example it actually provides a bogus graph - it actually should approach f(x,y) = 1 for large x and y (since 1/(x^2+y^2) is small for large x,y; hence sin(1/(x^2+y^2)) can be approximated by 1/(x^2+y^2), resulting in f(x,y) -> 1 for large x,y). Also I've adjusted the plot range a bit, since this then actually shows the "interesting" center of the function (x=y=0).	2017-08-11 03:38:20 +02:00
Martin Thoma	7740f0147f	Remove trailing spaces ... The commands find . -type f -name '*.md' -exec sed --in-place 's/[[:space:]]\+$//' {} \+ and find . -type f -name '*.tex' -exec sed --in-place 's/[[:space:]]\+$//' {} \+ were used to do so.	2015-10-14 14:25:34 +02:00
