You mean, "N in 45 degrees"? Ans. sine(45) = 0.7071 N
It can. The sine function is defined for all numbers--negative, 0, and positive. The function is periodic and repeats every 360 degrees.
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.
sine 810 = sine 90 = 1
No; those could be three different values, or sometimes two of them might be the same. For example, if the angle is 45 degrees, the values are about... cos:0.707 sin: 0.707 tan: 1 For 45 degrees, the cosine and sine are the same. For 36 degrees, cos:0.809 sin: 0.588 tan: .727
√ 1/2 = sine(45)= cosine(45) -Key
By shifting the sine wave by 45 degrees.

The sine and cosine of acute angles are equal only for 45° sin45° = cos 45° = 1/sqrt(2) = 0.7071
The square root of two over two.
at a 45 degree angle, or pi/4
1 it can not used when the angle more than 45 degrees.....
We know that sin @ = h/l is the basic principle of working of sine bar.Differentiating above equation,.. . cos @ . d@ = l.dh - h.dl_________ l*ld@ =tan@(dh/l - dl/l)This indicate that error is a function of tan @ and below 45 degree error is smaller which suddenly increases above 45 degree. because of this reason sine bar is preferred for measuring angle below 45
0.70710678118654752440084436210485 ----------------------- Improve: If you mean 45 degrees then it equals: Sqrt (2) /2 (which is the exact form of the above approximate form)

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