• Gram determinant
• Buzano's inequality
• Integral inequalities
• Discrete inequalities
• Lagrange multipliers

In this paper we take a refreshing look at a Cauchy-Schwarz type inner product inequalities. We also provide a Cauchy-Schwarz based proof and a refinement of Buzano's inequality in inner product spaces. Some elementary applications such as trace inequalities for unitary matrices and discrete or integral inequalities are given.
