If I wanted to consider cases where the solutions were constrained by relationships amongst remaining parameters then I could utilize another command, eg. eliminate. S := solve(eqs,[a[0],a[1],b[1],alpha[1],beta[1],c]): WebSearch for roots only in the specified interval. The ranges are closed intervals. That is, the endpoints are included in the range. The left-hand side of each equation must be a variable name, unless equations is a list of procedures in which case only the right-hand side range values must be provided. The right-hand side is the corresponding interval to search.
