O, 30, 45, 60 and 90 degrees are angles which are used very often in problems. The angles in Sine Cosine Tangent are given in the order of 0°, 30°, 45°, 60°, and 90°. You can remember the value of Sine-like this 0/√2, 1/√2, 2/√2, 3/√2, 4/√2. The row of cosine is similar to the row of sine just in reverse order. Each value of tangent can be obtained by dividing the sine values by cosine as Tan = Sin/Cos.
