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)
No. As the angle increases from zero to 90 degrees,its sine increases from zero to '1'.
The sine of a complementary angle can be found using the relationship that the sine of an angle is equal to the cosine of its complement. Since the complementary angle of 28 degrees is 62 degrees (90 - 28 = 62), the sine of 62 degrees is equal to the cosine of 28 degrees. Therefore, (\sin(62^\circ) = \cos(28^\circ)).
sine(15 degrees) = 0.25882 (rounded)
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.
Multiply the speed by the cosine of the angle (25 degrees in this case). For the vertical velocity, multiply by the sine of 25 degrees.Multiply the speed by the cosine of the angle (25 degrees in this case).

The sine of 22.5 degrees is 0.383
No. As the angle increases from zero to 90 degrees,its sine increases from zero to '1'.
the sine of a 30 degree angle is 0.5
The sine of a complementary angle can be found using the relationship that the sine of an angle is equal to the cosine of its complement. Since the complementary angle of 28 degrees is 62 degrees (90 - 28 = 62), the sine of 62 degrees is equal to the cosine of 28 degrees. Therefore, (\sin(62^\circ) = \cos(28^\circ)).
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.

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.

94.5 degrees
sin-1(0.707) = 44.99134834 or about 45 degrees
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.
