How do you simplify sin 60?

The exact value of sin60° as a simplified fraction is √3 /2.

Is the sin of 60 and 120 the same?

As the value of sine function in the second quadrant takes the positive value, the value of sin 120 degrees should be a positive value. By looking at the diagram given above, the value of sin 60 is equal to the value of sin 120. It means that, sin 60 = sin 120 = √3/2.

Why is sin60 negative?

Trigonometry Examples Make the expression negative because sine is negative in the fourth quadrant. The exact value of sin(60) is √32 .

Is sin60 Cos 30?

sin 60° = √3/2. cos 30° = √3/2. = 3/4.

What is the value of sin ∅?

The exact value of sin 180 is zero. Sine is one of the primary trigonometric functions which helps in determining the angle or sides of a right-angled triangle. It is also called trigonometric ratio.

What is the value of sin 60 by 2?

The exact value of sin(60) is √32 .

What is 60 in its simplest form?

Answer: 60% as a fraction in simplest form is 3/5 Let us look at these three steps below.

How do you find COS 120 without a calculator?

The value of cos 120 degrees can be calculated by constructing an angle of 120° with the x-axis, and then finding the coordinates of the corresponding point (-0.5, 0.866) on the unit circle. The value of cos 120° is equal to the x-coordinate (-0.5). ∴ cos 120° = -0.5.

What angle is sin 120?

Sin 120 degrees is the value of sine trigonometric function for an angle equal to 120 degrees. The value of sin 120° is √3/2 or 0.866 (approx).

What is value of cos 120 degree?

Value of Cos 120 is -½. It has many other applications too.

Can you take sin of a negative?

It works only for angles between 0 and 90 degrees. This definition allows sine to take negative values because the vertical coordinate will be negative in the two bottom quadrants.

Why is the sin of 90 degrees 1?

Start measuring the angles from the first quadrant and end up with 90° when it reaches the positive y-axis. Now the value of y becomes 1 since it touches the circumference of the circle. Therefore the value of y becomes 1. Therefore, sin 90 degree equals to the fractional value of 1/ 1.

What is the opposite of 60 degrees?

The opposite of a 60-degree angle is also a 60-degree angle (vertically opposite angles). Because opposite angles are equal.

Why is sin 30 a half?

Now observe that the triangle ABD is a right triangle, right-angled at D with ∠BAD = 30° and ∠ABD = 60°. Therefore, Sin 30 degree equals to the fractional value of 1/ 2. In the same way, we can derive other values of sin degrees like 0°, 30°, 45°, 60°, 90°,180°, 270° and 360°.

What is the COS for 30?

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.

What is a sin of 30?

Sin 30 degrees is the value of sine trigonometric function for an angle equal to 30 degrees. The value of sin 30° is 1/2 or 0.5.

Why is PH a sin?

Because on the unit circle, the hypotenuse is 1. Because similar triangles, multiplying the hypotenuse by any amount will also multiply any other side by that amount.

What are the 5 key points of sin?

The values of sin x correspond to the y-values, so those key points are (angle, y-value) or (0,0), (π/2, 1), (π, 0), (3π/2, -1), (2π, 0).
