I've been doing many TikZ diagrams lately and every so often I encounter a situation where I am forced to use some temporary coordinate in a \path. In the following short example, the problem is ...
This question has two parts: why is the angle computed always 0 (should be 45) what is a straightforward way to compute distance between coordinates (there is How can I compute the distance between ...
Given two points (defined, for instance using nodes), I want to compute the distance between them. Is there some build in functionality in tikz to do this? If not, how can it be done using the ...
When can I use functions and do calculations in TikZ? How do I make this work: \draw (0,0) arc(0:90:sqrt(15)); %not ok why is this working: \draw (0,0) arc(0:asin(1):5); %ok with ...
