📌 Understanding Secant Calculation

The secant function calculates the reciprocal of the cosine function. The formula is:

  • sec(θ) = 1 / cos(θ)
  • Secant is undefined when cos(θ) = 0.

❓ FAQs

Q1: How do I calculate secant?
✅ Use the formula sec(θ) = 1 / cos(θ)

Q2: What is the secant of 0°?
✅ sec(0°) = 1

Q3: Can secant be undefined?
✅ Yes, secant is undefined at 90° and 270° because cos(θ) = 0 at these points.

Q4: Where is secant function commonly used?
✅ It is widely used in **engineering, physics, and astronomy**.

Q5: Why is secant function important?
