Please help
How can I for the following inequality
(cosq1.cosq1) + (cosq2.cosq2) +(cosq3.cosq3) - 2 cosq1 cosq2 cosq3 - 1≤0
Drive the following inequality
cosq1 cosq2 – sqrt[(sinq1.sinq1)(sinq2.sinq2)] ≤ cosq3 ≤ cosq1 cosq2 +
sqrt[(sinq1.sinq1)(sinq2.sinq2)]
above inequality is for a polyhedral with 4 vertices (with all vertices connected)and for any vertix above holds
Please help
sqrt==> square root
