There is no particular meaning associated with theta - it will depend on the context.
Theta means 't' or 'th' and sigma means 's'.
assuming that you mean what is theta if sin 4 theta = 0 then then theta=0, 0.25pi, 0.5pi, 0.75pi... if not then without additional information the best answer you can get is sin4theta=sin4theta
Theta is just a Greek letter used to denote measurement of angle. Sine is a trigonometric function, i.e., the ratio of the side opposite to the angle theta to the hypotenuse of the triangle. So Sine theta means the value of sine function for angle theta, where theta is any angle.
'Theta' is a zero-looking Greek letter with a line across. It is used in physics and many mathematic equasions.
"Theta" is a letter in the Greek alphabet. In fact, it is the eighth letter in the alphabet. It was originally derived from teth, a Hebrew letter.
Theta is most often used to represent unknown angles, especially in the study of trigonometry. Theta represents an angle in degrees, but not in radians. --------------------------------------- Theta (θ) is a Greek letter, typically denoting an unknown angle. Depending on the context of the problem, it could be in degrees or radians.

theta means u and any ways no such thing
If by theta you mean the angle at the base of slope on which is the body laying, and you want to calculate minimal theta for which the blocks starts to slide: Let's first calculate: weight: Q = mg force normal to the slope: N = Q cos theta = mg cos theta force tangent to the slope: F = Q sin theta = mg sin theta force of friction: T = fN = fmg cos theta, where f is coefficient of friction The body will start to move downwards, when T = F, or: fmg cos theta = mg sin theta which after simplyfying becomes: f cos theta = sin theta, f = sin theta / cos theta f = tan theta Therefore, theta = arc tan f As you see, the angle only depends on friction coefficient f. (If that's not a problem you asked to be solved, edit your question please to precisely state what needs to be calculated)

Lots of alpha-theta brain wave activity typically indicates a relaxed or daydreaming state rather than a stressed one. Alpha waves are associated with a calm and relaxed mind, while theta waves are linked to a deeply relaxed or meditative state.
