Three common trigonometric ratios are the sine (sin), cosine (cos), and tangent (tan). These are defined for acute angle A A below: In these definitions, the terms opposite, adjacent, and hypotenuse refer to the lengths of the sides.What is the cosin of 60? Cos (60) = -0.95241 assuming that angles are measured in radians, as would be done by most mathematicians. If they are measured in degrees, the answer is 0.5.Aug 16, 2023 · Transcript. Ex 8.2, 1 Evaluate the following : (i) sin 60° cos 30° + sin 30° cos 60° We know that, sin 60° = √3/2 cos 30° = √3/2 sin 30° = 1/2 cos 60° = 1/2 Putting all values sin 60° cos 30° + sin 30° cos 60° = (√𝟑/𝟐)× (√𝟑/𝟐)+ (𝟏/𝟐)× (𝟏/𝟐) = (√3 × √3)/ (2 × 2)+1/ (2 × 2) = 𝟑/𝟒 + 𝟏 ... .
