Questions & Step-by-Step Solutions

If sec θ = 2, what is the value of cos θ?
  • Step 1: Understand that sec θ is the reciprocal of cos θ. This means sec θ = 1/cos θ.
  • Step 2: If sec θ = 2, we can write the equation as 2 = 1/cos θ.
  • Step 3: To find cos θ, we need to rearrange the equation. Multiply both sides by cos θ: 2 * cos θ = 1.
  • Step 4: Now, divide both sides by 2 to isolate cos θ: cos θ = 1/2.
  • Trigonometric Functions – Understanding the relationship between secant and cosine functions.
  • Reciprocal Identities – Applying the reciprocal identity that sec θ = 1/cos θ.
