For angles greater than 360 degrees, subtract multiples of 360 so that the relevant angle (the remainder) is between 0 and 360 degrees.
Then
For 90 < x ≤ 180 deg, sin(x) = sin(180-x)
For 180 < x ≤ 270 deg, sin(x) = -sin(x-180)
For 270 < x ≤ 360 deg, sin(x) = -sin(360-x)

Is sine greater than one?
No angle has a sine function greater than 1.
Why sinθ value is less then and equal to one?
If you look at the definition of the sine function in a triangle, you'll discover that the maximum possible value of the sine function is ' 1 ' and the minimum possible value is ' -1 '. There's no angle that can have a sine greater than ' 1 ' or less than ' -1 '. So the absolute value of the sine of anything is always ' 1 ' or less.
Cosecant on calculator?
Cosecant is the reciprocal of sine. To find the cosecant of an angle using a calculator, find the sine of that angle (using the Sin button) and then divide 1 by the result.
What is the sine of 180?
The sine of 180 degrees is 0. Remember, the sine value on a unit circle is the y-value. If you find f(pi) in the function f(x)=sin(x), you will get zero as an answer.
How do you find the size of an angle when you have only the sine of the angle?
You use the arcsine or sin-1 function. For any value of sin(X), the function will return a value for the angle in the range [-pi/2, pi/2]. There are, however, infinitely many angles which will have the same value for sine. They are X + 2k*pi and (2k+1)*pi - X radians where k is any integer. If you still work with degrees, the answers are X + 360k and (2k+1)*180 - X degrees.
