#include "TLatex.h" #include "TCanvas.h" void drawMathSymbols() { TCanvas *c = new TCanvas("c", "Math Symbols", 800, 600); c->cd(); TLatex *text = new TLatex(); text->SetNDC(); text->SetTextSize(0.05); text->DrawLatex(0.5, 0.5, "#alpha_{i}^{2} + sin(#theta) - #sqrt{#frac{E}{m_{0}}} #geq 10^{4}"); c->SaveAs("MathSymbols.pdf"); delete text; }This code creates a canvas and draws mathematical symbols using TLatex. The `SetNDC()` function is used to set the normalization factor of the canvas, `SetTextSize()` sets the size of the text in the canvas, and `DrawLatex()` draws the mathematical expression with the given syntax. This example uses ROOT CERN libraries which include TLatex.h header file.
