cot 60 ° = 1 / tan 60° = 1/ √3. Then, the value of Use sum and difference formulas for cosine. Finding the exact value of the sine, cosine, or tangent of an angle is often easier if we can rewrite the given angle in terms of two angles that have known trigonometric values. Since it is true that the sin of supplementary angles have equal values and the sin function was used to find angle B, you have to check if another triangle may exist with angle A measuring 19 degrees and and angle B measuring 18 degrees.

sin 2 45 ° + cos 2 45 ° = (1 + 1) / 2. sin 2 45 ° + cos 2 45 ° = 2 / 2. sin 2 45 ° + cos 2 45 ° = 1. Problem 6 : Find the value of sin 30 ° ⋅ csc 30 ° + tan 30 ° ⋅ cot 60 °. Solution : In the table above, sin 30° = 1/ 2. csc 30 ° = 1 / sin 30 ° = 2. tan 30 ° = 1/ √3. cot 60 ° = 1 / tan 60° = 1/ √3. Then, the value of
