How do you find the value of tan15?

Value of Tan 15

1. Tan (15°) can be found if we know the value of sin 15 degrees and cos 15 degrees.
2. From the above table, we have the values of tan, sin and cos ratios for 0°, 30°, 45°, 60° and 90°.
3. tan (15°) = √3 – 1/ √3 + 1.
4. Hence, the value of tan (15°) is √3 – 1/√3 + 1.
5. ∴ Tan (15°) = (1.732 – 1)/(1.732 + 1) = 0.2679.

What is cos15 in fraction?

The value of cos 15 degrees is 0.9659258. . .. Cos 15 degrees in radians is written as cos (15° × π/180°), i.e., cos (π/12) or cos (0.261799. . .). In this article, we will discuss the methods to find the value of cos 15 degrees with examples. Cos 15°: 0.9659258. . . Cos 15° in fraction: (√6 + √2)/4.

How do you find sin15?

Value of sin 15

1. Value of sine 15 degrees can be evaluated easily.
2. The actual value of sin 15 degrees is given by:
3. Sin P/2 + Cos P/2 = ± √ (1 + sin P)
4. Sin 15° + Cos 15° = ±√ (1 + sin 30) …(
5. Sin P/2 – Cos P/2 = ± √(1 – sin P)

How do you find the value of sin 106?

Using trigonometric identities, we can write cos 106° in terms of sin 106° as, cos(106°) = -√(1 – sin²(106°)). Here, the value of sin 106° is equal to 0.9613.

How do you find sin 74?

The sin of 74 degrees is 0.96126, the same as sin of 74 degrees in radians. To obtain 74 degrees in radian multiply 74° by π / 180° = 37/90 π. Sin 74degrees = sin (37/90 × π).

How do you write sin 15?

Value of Sin 15 in Decimal Since, we know, Sin 15° = (√3–1)/2√2.

How do you solve sin 150?

How to Find the Value of Sin 150 Degrees? The value of sin 150 degrees can be calculated by constructing an angle of 150° with the x-axis, and then finding the coordinates of the corresponding point (-0.866, 0.5) on the unit circle. The value of sin 150° is equal to the y-coordinate (0.5). ∴ sin 150° = 0.5.

How do you find the exact value of cos15?

Answer: The value of cos 15° = (√3+1)/2√2.
