WebA trigonometric identity is an equation involving trigonometric functions that is true for all angles for which the functions are defined. We can use the identities to help us solve or … Web∴ Tan (15°) = (1.732 – 1)/ (1.732 + 1) = 0.2679 Or tan (15°) ≈ 0.27 Tan 15° With Respect To sin and cos function Similarly, we can also find the value of tangent 15 degrees, by knowing the value of sin 15 and cos 15 degrees. Tan (15°) = sin 15/cos 15 Tan 15° = sin 15/cos 15 Sin 15° = sin (45 – 30)° and cos 15 = cos (45 – 30)°
