Manim MathTex 沒有給出微分方程的正確 output

Question

所以我想要如圖所示的微分方程的 output 但我沒有得到正確的方程 output 我也嘗試了 latex 代碼但仍然無法正常工作

from manim import *


class CreateCircle(Scene):
    def construct(self):
        eq_one = MathTex("a^{2}+b^{2}=1")
       
        eq_two= MathTex("\\frac{\text{d}^{2}x}{\text{d}y}","+","\\frac{\text{d}^{2}y}{\text{d}x}=","1")
        eq_two.next_to(eq_one,DOWN)
        self.wait()
        self.play(Write(eq_one))

        self.wait(3)
        self.play(Write(eq_two))
        self.wait(2)[output Image][1][Desired Image i want of differential equation][1]

歡迎來到 SO！ 您忘記轉義\字符。

from manim import *
class Test(Scene):
  def construct(self):
    eq_one = MathTex("a^{2}+b^{2}=1")
    
    eq_two= MathTex("\\frac{\\text{d}^{2}x}{\\text{d}y}","+","\\frac{\\text{d}^{2}y}{\\text{d}x}=","1")
    eq_two.next_to(eq_one,DOWN)
    self.wait()
    self.play(Write(eq_one))

    self.wait(3)
    self.play(Write(eq_two))
    self.wait(2)
