Step-by-step explanation:
Given Equation is [cos³θ + sin³θ/cosθ + sinθ] + [cos³θ - sin³θ/cosθ - sinθ]
= [cos⁴θ - cos³θsinθ + sin³θcosθ - sin⁴θ + cos⁴θ + cos³θsinθ - sin³θcosθ - sin⁴θ]/[cos²θ - sin²θ]
= [2cos⁴θ - 2sin⁴θ]/[cos²θ - sin²θ]
= 2[cos⁴θ - sin⁴θ]/cos²θ - sin²θ
= 2[(cos²θ - sin²θ)(cos²θ + sin²θ]/(cos²θ - sin²θ)
= 2[1]
= 2.
Hope it helps!
