What is the sin value of 60?

√3/2
Sin 60 degrees is the value of sine trigonometric function for an angle equal to 60 degrees. The value of sin 60° is √3/2 or 0.866 (approx).

What is the sin value of 30?

0.5
The value of sin 30 degrees is 0.5.

Is Sin 30 the same as cos 60?

According to the property of cofunctions (Topic 3), sin 30° is equal to cos 60°. The sine is the ratio of the opposite side to the hypotenuse.

How do you solve tan 30?

Tan 30 degree is equal to 1/√3 and its exact value is 0.57735.

What is the exact value of cos 30?

0.8660
Cos 30° = √3/2 Therefore, the exact value of cos 30 degrees is written as 0.8660 approx. √3/2 is the value of Cos 30° which is a trigonometric ratio or trigonometric function of a particular angle.

How are the sine 30 and its complement 60 related?

The cosine of an angle is defined as the sine of the complementary angle. The complementary angle equals the given angle subtracted from a right angle, 90°. For instance, if the angle is 30°, then its complement is 60°. cos θ = sin (90° – θ).

What is the value of cos 90 for sin 30?

For cos 1 cos 0° = sin 90° = 1 2 cos 30° = sin 60° = √3/2 3 cos 45° = sin 45° = 1/√2 4 cos 60° = sin 30° = 1/2 5 cos 90° = sin 0° = 0

What is sin 30 degrees?

Sin is a trigonometric ratio and the value of sin 30 degrees is half (½). Now the question arises what is a trigonometric ratio and how the value of sin 30 degrees is calculated. Trigonometric ratios is a part of trigonometry that deals with right-angled triangles. A triangle is a closed figure having three sides, three angles and three edges.

How do you find the value of sin 30?

Hence to find the answer of sin 30 value we need to know the length of all the sides of the triangle. So, let us suppose that AB=2a, such that half of each side is a. Sinϴ = Perpendicular Hypotenuse. Thus, the value of Sin 30 degree is equal to 12(half) or 0.5.

How do you prove sin 30 = 1/2?

In the simplest of terms – Sine of an angle (in a right angled triangle) is the ratio of the side length of the side present opposite to the angle in question, to the length of the hypotenuse (the longest side and also the side opposite to the right angle itself) To prove that sin 30 = 1/2, you could literally construct a right angled triangle ABC.
