# How to fix the error TeX capacity exceeded, sorry [input stack size=5000].?

I created a code of tikzpicture in Geogebra, but when I try to run it I am getting this error

! TeX capacity exceeded, sorry [input stack size=5000]. \font@name -> \T1/ptm/m/n/10 l.460 ...-20.0:380.0] {(\x,{sin((x°)*180/\pi)})};

If you really absolutely need more capacity, you can ask a wizard to enlarge me.

Here is how much of TeX's memory you used: 24821 strings out of 480790 625143 string characters out of 2905174 1149710 words of memory out of 3000000 40387 multiletter control sequences out of 15000+200000 598583 words of font info for 132 fonts, out of 3000000 for 9000 1141 hyphenation exceptions out of 8191 5000i,7n,9985p,744b,1555s stack positions out of 5000i,500n,10000p,200000b,50000s ! ==> Fatal error occurred, no output PDF file produced!

• You should type {sin(deg(x))} instead of {(\x,{sin((x°)*180/pi)})} Jul 21, 2020 at 11:11
• What is that °  doing there (in the function you're trying to plot)? Additionally I don't think scriptsize does anything here. Jul 21, 2020 at 11:14
• Problem solved? Apr 25, 2021 at 3:01

Here is my suggestion.

\draw[->] (0,-1.5)--(0,1.5) node[left]{$y$};
\draw[gray,thin,dashed] (0,1)--+(0:\b) (0,-1)--+(0:\b) (pi/2,0)--+(90:1) (3*pi/2,0)--+(-90:1);
\draw[smooth,red]  plot[domain=-\a:\b] (\x,{sin(\x r)});
\path
