Solving Equations Numerically

Description

If it is not possible to find an exact solution to an equation or equations specified, one can use find_root to find a numerical solution. For example, solve does not return anything interesting for the following equation:

sage: theta = var('theta')
sage: solve(cos(theta)==sin(theta), theta)
