import { MathJaxSvg } from 'react-native-mathjax-html-to-text-svg';
...

<MathJaxSvg 
  fontSize={16}
  color="red"
  fontCache={true}
>
  {'$$4sen(α)cos^2(α/2)$$'}

Using TeX or LaTeX with html

import { MathJaxSvg } from 'react-native-mathjax-html-to-text-svg';

return (

Output

Props	Default	Description
fontSize	14	The font size for displaying the formula. Note that it will also apply to regular text. Regular text can accept inline styles if HTML has inline styles.
color	"#000000"	The color of the formula to display. Note that it will also apply to regular text. Regular text can accept inline styles if HTML has inline styles.
fontCache	false	MathJax will cache font paths on an expression-by-expression basis (each expression has its own cache within the SVG image itself), which makes the SVG self-contained, but still allows for some savings if characters are repeated.
style	{ flexDirection: 'row', flexWrap: 'wrap', alignItems: 'center', flexShrink: 1 }	Container style
