(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

Use the Cauchy-Schwarz inequality to prove that for all real values of a, b, and theta (which ill denote as θ),

(a cosθ + b sinθ)^{2}≤ a^{2}+ b^{2}

2. Relevant equations

so the Cauchy-Schwarz inequality is | <u,v>| ≤ ||u|| ||v||

3. The attempt at a solution

I'm having a difficult time figuring out what is myuand myv. Sorry for the stupid question.

Thank you for any guidance.
