Q. Simplify to a single trig function with no denominator.\newlinecos⁡θ⋅sec⁡θ \cos \theta \cdot \sec \theta \newlineAnswer:
  1. Express as 1cos⁡(θ)\frac{1}{\cos(\theta)}: Express sec⁡(θ)\sec(\theta) in terms of cos⁡(θ)\cos(\theta) as sec⁡(θ)=1cos⁡(θ)\sec(\theta) = \frac{1}{\cos(\theta)}.
  2. Substitute in expression: Substitute sec⁡(θ)\sec(\theta) with 1cos⁡(θ)\frac{1}{\cos(\theta)} in the given expression to get cos⁡(θ)⋅(1cos⁡(θ))\cos(\theta)\cdot\left(\frac{1}{\cos(\theta)}\right).
  3. Simplify to 11: Simplify cos⁡(θ)⋅(1/cos⁡(θ))\cos(\theta)\cdot(1/\cos(\theta)) to get 11, since cos⁡(θ)\cos(\theta) in the numerator and denominator cancel each other out.
