    sinusoidal inequalities

    How can I from the following inequality

    (cosq1cosq1) + (cosq2cosq2) +(cosq3cosq3) - 2 cosq1 cosq2 cosq3-1 ≤ 0

    Drive the following inequality
    cosq1 cosq2 sqrt[(sinq1sinq1)(sinq2sinq2)]≤ cosq3 ≤ cosq1 cosq2 +sqrt[(sinq1sinq1)(sinq2sinq2)]


    sqrt == square root

    Please help

    Are you sure this isn't supposed to be in the University section? If nobody has answered it yet, you might have to post it there
