sqrt 2 / 2 is the answer.
at a 45 degree angle, or pi/4
sin-1(0.707) = 44.99134834 or about 45 degrees
1 it can not used when the angle more than 45 degrees.....
sine 45 = 0.850903525
The number 1.414... (square root of 2) is two times the cosine or sine of a 45 degree angle. The reason for this is that for a 45 degree angle, the two sides are cosine and sine, they are equal, and if you solve using the Pythagorean theorem with a hypotenuse of 1, the two sides are each (21/2)/2.
√ 1/2 = sine(45)= cosine(45) -Key
the sine of a 30 degree angle is 0.5
the sine of an angle can't be greater than 1.0
Use and rearrange the sine ratio: 30*sin(45) = 21.21320344 units
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.
It can. The sine function is defined for all numbers--negative, 0, and positive. The function is periodic and repeats every 360 degrees.
It is 1.
