First Steps

This is meant to be a gentle introduction to the symengine C++ library.

Working with Expressions

We will start by inspecting the use of Expression

#include <symengine/expression.h>
using SymEngine::Expression;

Expression x("x");

auto ex = pow(x+sqrt(Expression(2)), 6);
ex

$${(x+\sqrt{2})}^6$$

expand(ex)

$$8+24\sqrt{2}x+40\sqrt{2}{x}^3+6\sqrt{2}{x}^5+60x^2+30x^4+x^6$$
