Dec 16, 2024 · Example 11 Find the value of sin 15°. sin 15° = sin (45° – 30°) = sin 45° cos 30° – cos 45° sin 30° = 1/√2 × √3/2 −1/√2 × 1/2 = 1/√2 ( (√3 − 1)/2) = (√𝟑 − 𝟏)/ (𝟐√𝟐) Davneet Singh has done his B.Tech from Indian Institute of Technology, Kanpur. …

Feb 26, 2017 · In a triangle which has one angle of 90 degrees, the sine of the angle of 15° is the ratio of the length of the opposite side o to the length of the hypotenuse h: sin 15° = o/h.

Finding the value of sin 15° - Maths. The original value of sin15° = (√3 – 1) / 2√2. This value of sin15° can be obtained through different methods. To solve for the sine value, the following values of sine and cosine functions for some standard angles must be considered: sin0° = 0; sin30° = ½; sin45° = 1/√2; sin60° = √3/2 ...

The sine of 15 degrees, abbreviated sin 15°, is a trigonometric function that expresses the ratio of the length of a right triangle’s side opposite a 15-degree angle to the length of the hypotenuse. It is an irrational number that is roughly equivalent to 0.2588.
