iOSMath is an open source component from Kostub Deshmukh for displaying math equations in iOS applications within a UILabel type class.

Equations in iOSMath are created using the popular LaTeX mathematics markup format and the following formula types are supported by the library according to the readme:

*Simple algebraic equations**Fractions and continued fractions**Exponents and subscripts**Trigonometric formulae**Square roots and n-th roots**Calculus symbos – limits, derivatives, integrals**Big operators (e.g. product, sum)**Big delimiters (using \left and \right)**Greek alphabet**Combinatorics (\binom, \choose etc.)**Geometry symbols (e.g. angle, congruence etc.)**Ratios, proportions, percents**Math spacing**Overline and underline**Math accents**Matrices**Equation alignment**Most commonly used math symbols*
