What is the exact value of sin 180?

zero
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.

How is sin 180 theta sin theta?

Since sin(180°)=0 and cos(180°)=−1, we get sin(180°−θ)=0−(−1)sin(θ)=sin(θ).

Is sin 180 undefined?

csc(180°)=1sin(180°)=10 . Because we’re dividing by 0, it is undefined. If we tried to make a right triangle on the unit circle with points at the origin, or (0,0) , and the point (1,0) with an angle of 180°, our third point would be (−1,0) .

What is the sin 60 degree?

Sin 60 Degree Value As we know, the most commonly used primary functions of trigonometry are Sine, Cosine, and Tangent. The sin 60 degree exact value and another trigonometry ratio with different degrees such as 45°, 60°, 90°, and 180° are most commonly used in trigonometry equations. We will review sin 60 degree exact value in this article.

What is the formula for Sinsin 60?

Sin 60 Formula 1 Sin 0° = √0/4 = O 2 Sin 30° ==√1/4= ½ 3 Sin 45° =√2/4= ½ 4 Sin 60° = √3/4 = √3/2 5 Sin 90° = √4/4 = 1

What is the sine of 180 degrees?

The sine of 180–60 is the sine of 120 which is 30 degrees more than the peak of 90 degrees. At 90 degrees the sine vale will decreease at an even rate whether you go clockwise or counterclockwise from 90 degrees. In one instance you’re going counterclockwise by 30 degrees while in the other instance you’re going clockwise by 30 degrees.

What is the sin 60 of a right angle triangle?

In the right angle triangle, Sin 60 value is the ratio of the length of the perpendicular side to the length of the hypotenuse. Based on the above diagram, The ratio of Sin 60 = Perpendicular/ Hypotenuse. The method to calculate the Sin 60 degree exact value is to divide √3 by √4 or √3/√4. With this, we got Sin 60 value= √3 /2
