Sine 3.3 degrees is about 0.057564. Sine 3.3 radians is about -0.157746. Sine 3.3 grads is about 0.051813.
A sine wave is the graph of y = sin(x). It demonstrates to cyclic nature of the sine function.

-- sin(x) is a number. It's the sine of the angle 'x'. -- sin-1(x) is an angle. It's the angle whose sine is the number 'x'.
It is simply the sine of the supplementary angle. If x is an angle measuring (90, 180) degrees, then sin(x) = sin(180 - x).
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.
That's right. cosecant(x) = 1 / sine(x), so you would get a division by zero.
The answer will depend on where, in the sine function, the x-value appears: For example, its roles in f(x) = sin(x), or f(x, theta) = x*sin(theta) or f(x, theta) = sin(x*theta) f(theta) = sin(theta + x) are quite different.
There is no real significance to sine plus cosine, now sin2(x) + cos2(x) = 1 for any x, where sin2(x) means to take the sign of the number, then square that value.
The rms value of a sine wave current is 0.707 Imax. So the answer to your quesion is 0.707 x 4 = 2.83 A.
Effective = RMS= average Not for a sine wave it isn't. The r.m.s. value of a sine wave is 1.11 x the average, or mean, value. The "effective" value is not a term which I've seen in any of my reference books.
Because the argument of the sine function can have any real value. In fact, it can extend beyond that but that is for more advanced level students.
In trigonometry, the value of R is the radius of the circle, and is usually normalized to a value of 1. If the circle is at the X-Y origin, and theta is the angle between the radius line R, and X and Y are the X and Y coordinates of the point on the circle at the radius line, then... sine(theta) = Y / R cosine(theta) = X / R secant(theta) = 1 / cosine(theta) = R / X cosecant(theta) = 1 / sine(theta) = R / Y

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.
