The sine of 22.5 degrees is 0.383
1 it can not used when the angle more than 45 degrees.....
Sine = Opposite divided by Hypotenuse Opposite is the side of the triangle opposite the angle (in this case the 90o angle). Hypotenuse is the side opposite the right angle in a right angle triangle. Therefore, Sine 90 = 1 because the opposite side and the hypotenuse are the same side, they are both opposite the right angle.
Rearrange the sine ratio of sine = opposite/hypotenuse: hypotenuse = opposite/sine hypotenuse = 12/sine 30 degrees = 24 Therefore the hypotenuse is 24 units in length.
It means that the angle in question is any multiple of 180 degrees.
sine-1(0.3420201433) = 20 degrees
225 degrees
Sine of 225 degrees = - 0.5 sqrt(2)
No. As the angle increases from zero to 90 degrees,its sine increases from zero to '1'.
To find the quadrant and sign of the cotangent function for -495 degrees, first, convert it to a positive angle by adding 360 degrees until the angle is within the standard range. -495 + 720 = 225 degrees. The angle 225 degrees is in the third quadrant, where both sine and cosine are negative, making cotangent (which is the ratio of cosine to sine) positive. Thus, cot(-495 degrees) is positive and located in the third quadrant.
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.
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.
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.
An acute angle that is 1/4 of a right angle
