WebMar 25, 2015 · About this tutor ›. Hi, David. The half angle formula: cos (θ/2) = ±√ ( (1 + cosθ)/2). Since sinθ = 3/5, cosθ = 4/5. Therefore, (1+cosθ)/2 = 9/10, and cos (θ/2) = ±√.9. Since 0 &lt; θ &lt; π, we know that 0 &lt; θ/2 &lt; π/2, and cos (θ/2) is positive, cos (θ/2) = √.9 = 0.9487. I hope this helps. Upvote • 0 Downvote. Add comment.
