GSoC 2016 Application Shekhar Prasad Rajak: Solvers - Completing Solveset

SymPy is a Python library for symbolic mathematics. Solvers module is mostly used module, so it is very important that Solver works perfectly and give all solution. Harsh Gupta( GSoC 2014) and Amit Kumar (GSoC 2015) have worked on Solveset submodule. Solveset returns a set object and a set object takes care of all types of output. But to make Solveset fully functional, need to implement Non-linear multivariate Equation and System of multivariate Equation solver, System of Inequality solvers, Transcendental Equation solver and have to improve solve_trig, _invert methods . So in this summer I want to implement these remaining things, to complete Solveset.
