How do you derive the values of sine, cosine, and tangent for common angles such as 30 degrees, 45 degrees, and 60 degrees?

Tracy Wright
To derive sine, cosine, and tangent values for 30°, 45°, and 60°, use special right triangles. For 30° and 60°, use a 30-60-90 triangle where sides are 1, √3, and 2. For 45°, use a 45-45-90 triangle where sides are 1, 1, and √2. Apply SOH-CAH-TOA to find trigonometric values.
