\sqrt issue

Hello I was trying to do an animation using square roots, but when i write the code like this: TexMobject(r"\sqrt{",r"\left(",r"5",r"-",r"{9",r"\over",r"2}",r"\right)",r"^2}",r"=",r"\sqrt{",r"\left(",r"4",r"-",r"{9",r"\over",r"2}",r"\right)",r"^2\tiny.}") And then Writing (or adding) on the scene, it shows the whole equation, except the last character (the “2” exponent).

I watch a video that use a “\tiny .” to solve this, but it doesn’t work to me.

I’m using Windows 10, the last version of Manim.

Update on my solution.

I haven’t really found anything yet, admittedly due to minimal reflection on the issue but I have stumbled upon something.

That method somehow has to stay because it makes the tex_to_color_map work so if you wanted to use that that may be a problem.

Again, if I come up with anything is a fingers crossed protocol. Hopefully someone else beats me to the chase.

Hello,

it seems, that manim is expecting at least one character after the { of \sqrt{. So I tried to add a space in Tex. This can be one of these codes:

\, \: ~

The space is barely visible in the output but it worked for me.

from manim import *
config.background_color = WHITE


class Formel(Scene):
    def construct(self):

    u_formel_1b = MathTex(
            "\\hat{u} = \\sqrt{\,",
            "\\hat{u}_{R}^{2}",
            " + ",
            "\\hat{u}_{C}^{2}}}",
            color= BLACK
        )
    u_formel_1b[1].set_color(GREEN)

    self.play(Write(u_formel_1b))
    self.wait(5)
