Tan 18 degree

∴ tan 18° = tan(0.3141) = √(25 - 10√5)/5 or 0.3249196. . . Explanation: For tan 18 degrees, the angle 18° lies between 0° and 90° (First Quadrant). Since tangent function is positive in the first quadrant, thus tan 18° value = √(25 - 10√5)/5 or 0.3249196. . .

How do you find an angle of 18 degrees?

So it's starting 0. 10 15 16 17 18. So this is 18 degree now joining this side to get 18 degree

What is the value of cot 18 degree in fraction?

What is the value of sin 18 in fraction?

The value of sin 18° is equal to the y-coordinate (0.309). ∴ sin 18° = 0.309.

Is the value of sin 18 degree?

Sin 18 value in radians is equal to -0.769214 (approx). This value can be calculated by converting the radians measure value to degree measure.

Is the value of cos 18?

The value of cos 18° is equal to the x-coordinate (0.9511). ∴ cos 18° = 0.9511.

What is a complement of 18 degrees?

So 18 degrees plus X is 90 degrees well if you subtract 18 from both sides we'll get x equals 72

What is an angle with 18 sides?

An 18-sided polygon, sometimes also called an octakaidecagon.

How do you prove sin 18 degrees?

Exact Value of sin 18°

How to find exact value of sin 18°?
Let A = 18°
Therefore, 5A = 90°
⇒ 2A + 3A = 90˚
⇒ 2θ = 90˚ - 3A.
Taking sine on both sides, we get.
sin 2A = sin (90˚ - 3A) = cos 3A.
⇒ 2 sin A cos A = 4 cos^3 A - 3 cos A.

What is 18 simplified?
