Use the half angle form, which states that:

sin(x/2) = √((1 - cos(x))/2)

Then:

x/2 = 157.5

x = 315

You should get:

sin(315 / 2) = √((1 - cos(315))/2)

= √((1 - 1/√2)/2)

Does the sine of an angle decreases as the angle increases from 0 degrees to 90 degrees?

No. As the angle increases from zero to 90 degrees,its sine increases from zero to '1'.


What is the value of the sine ratio for the angle 15 degrees?

sine(15 degrees) = 0.25882 (rounded)


What is the value of the sin?

If you mean the sine function, it is dependent on an angle. For example, the sine of an angle of zero degrees is zero; the sine of an angle of 90 degrees is one; for an angle of 180 degrees, the sine is again 0; if you make a graph, you get a curve that looks like a wave. In general, the values the sine function can take are between 1 and -1, inclusive.


What is the horizontal velocity of 25 degrees?

Multiply the speed by the cosine of the angle (25 degrees in this case).

Is the sine of an angle positive?

The sine of an angle between 0 and 180 degrees is positive. The sine of an angle between 180 degrees and 360 degrees is negative. At 0, 180 and 360 degrees the sine is 0.The sine is a periodic function with period 360 degrees, so angles differing by a multitude of 360 degrees have the same sine. Hence, for instance, the sines of the angles 0, 360, 720, ... are equal, namely 0.In any right triangle the sine of one of the non-right angles will be positive, since these are greater than 0 and less than 90 degrees.

Is the sine of an acute angle is greater that 1?

No. The sine of an acute angle is less than 1. An acute angle is less than 90 degrees. The sine of 0 degrees is 0, and the sine of 90 degrees is +1. So the sines of the angles between 0 degrees and 90 degrees are less than 1.

Is sine of an angle directly proportional to an angle?

No. The sine of an angle is not directly proportional to the angle. It is a function of the angle, but it is periodic, repeating every 360 degrees of the angle.

What angle has a sine of 0.13?

To find which angle has a sine of 0.13, you calculate arcsin or sin^-1(0.13) =7.47 degrees 7.47 degrees has a sine of 0.13. There is also another angle , below 360 , has a sine of 0.13. Subtract 7.47 from 180. 180-7.47 = 172.53 degrees also has a sine of 0.13.
