Class MyTrigoFunction is removed from file math_TrigonometricFunctionRoots.cxx. New class math_TrigonometricEquationFunction with the same functionality is created to provide possibilities for individual testing. Expressions for derivatives are corrected. New Draw command "intconcon" for intersection 2d conic curves is created. Test command OCC29289 (file QABugs_20.cxx) is created for individual testing math_TrigonometricEquationFunction. It is used in tests/bugs/modalg_7/bug29289
