What is the value of 120 degree?
What Is The Value Of Cos 120 Degree? Cos 120 degree is equal to minus half which can be written as (- ½ ) or (-0.5).
What is cos135?
The exact value of cos(135°) is -√(2) / 2. To find this, we use the angle sum identity for cosine, which is as follows: cos(X + Y) = cos(X…
What is the value of sin 2 pi by 3?
The exact value of sin(π3) sin ( π 3 ) is √32 .
Is the value of sin 60?
The exact value of sin(60°) sin ( 60 ° ) is √32 .
Is sin 1 the same as CSC?
Sine of an angle is the side of the triangle that does not touch the angle divided by the hypotenuse. … (note that arcsin is multi-valued, so arcsin(sin(x)) need not always be x). cosecant is the reciprical of the sin function or 1/sin(x) so that csc(x)*sin(x) = 1 when it is defined.
What is sin180?
Therefore, the value of sin 180 degrees = 0. The value of sin pi can be derived from some other trigonometric angles and functions like sine and cosine functions from the trigonometry table.
Is sin 1 the same as Arcsin?
Strictly speaking, the symbol sin-1( ) or Arcsin( ) is used for the Arcsine function, the function that undoes the sine. … Think of the Arcsine as the principal arcsine. Restrict the domain to take this inverse function. A function can only be an inverse if it is 1-to-1 and undoes exactly the desired function.
How do you solve cos 75?
Answer and Explanation: The value of cos(75°) is √6−√24 6 − 2 4 . Notice that we can write 75° as 30° + 45°.
What is the value of sin 120 in fraction?
sin 120° = sin(180° − 120°) = √3/2.
How do you find sin 120 without a calculator?
Use the unit circle and the fact that on the unit circle, sin A = y, and cos A = x. By drawing the unit circle it should be clear that sin(120) = sin(60) . If you know that sin(60) = sqrt(3)/2, then sin(120) = sqrt(3)/2. Originally Answered: How do you find sin 120 without a calculator?
Is the value of sin 120 degree?
Using the trigonometry formula, sin (90 + a) = cos a, we can find the sin 120 value. We know that the value of cos 30 degrees is √3/2. Therefore, sin 120° = √3/2.
What is the exact value of tan 120?
Answer and Explanation: The exact value of tan(120°) is -√(3). Since tan(120°) = tan(2 × 60°), we can use the tangent double-angle identity to…
What is sin 150 value?
First of all, observe that 150=180−30 . the answer comes from the fact that cos(30)=√32 and sin(30)=12 are known values.
What is sin 90 degrees in fraction?
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 exact value of sin 240 degrees?
sin (240) = sin (60 + 180) = – sin 60.
