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.

90 degrees = 1/4 of a turn

1 minute of arc is one sixtieth, or about 0.01667, of a degree. The sine of of 0.01667 degrees is about 0.0002909.
That is not correct: they are always LESS-THAN-OR-EQUAL to 1. They are also always greater-or-equal to minus 1.The fact that this is so follows directly from the definition. Two different definitions are commonly used:1) The sine is the y-coordinate of a unit circle (a circle of radius 1, with center at coordinates (0, 0)). The cosine is the x-coordinate of the same circle. The highest point on the circle has the y-coordinate 1 (at 90 degrees).2) In a right triangle, the sine is the side opposite to the angle considered, divided by the hypothenuse. The hypothenuse is of course longer than the other sides (except in the extreme case of 0 or 90 degree angles - this would not be properly called a triangle).
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. As the angle increases from zero to 90 degrees,its sine increases from zero to '1'.
cosecant = 1/sine csc 90 deg = 1/(sin 90 deg) = 1/1 = 1
The sign for a 90 degree is a small, perpendicular mark in the corner of the angle, to form a box with the angle.Also, the sine of 90 degrees is 1
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.
sine 810 = sine 90 = 1
sine-1(0.3420201433) = 20 degrees
Use the sine ratio: sine 30 degrees = opposite/hypotenuse Then: opposite = 2*sine 30 degrees Answer: 1 foot
You are referring to a special case of shape its called a line
90 degrees = 1/4 of a turn
The sine function outputs values between -1 and 1 for all angles. As the angle of a right triangle approaches 90 degrees, the length of the opposite side relative to the hypotenuse also approaches the length of the hypotenuse, which is the limit when sine = 1. Any angle below 90 degrees will have a ratio of opposite/hypotenuse less than or equal to 1.
