Calculate the area bounded by the curves y = eˣ, y = e⁻ˣ, and the line x = 1.

  • A. e + 1/e − 2
  • B. e − 1/e
  • C. e + 1/e
  • D. e − 1/e + 2

Answer: A) e + 1/e − 2

Explanation: Curves intersect at x=0. Area = ∫(0 to 1) (eˣ − e⁻ˣ) dx = [eˣ + e⁻ˣ] from 0 to 1 = (e + 1/e) − (1 + 1) = e + 1/e − 2 sq units.
