The evaluation engine can support equivalent forms of many constructs such as integrals, differentiation, summation, depth of function, etc.

Examples:

Expected |
Student |
Result |

g=f(0.5x) - 1 |
g=f(\frac{1}{2}x) - 1 |
true |

\frac{d}{dx}(2x+1)^3 |
6(2x+1)^2 |
true |

\int \frac{1}{x}dx |
\ln(x) |
true |

\int \frac{1}{x}dx |
x |
false |

These are in LaTex format, but the symbols can also be entered via the keypad.

Symbols for summation are on the page to the left.
