# What does 'theta' mean in statistics?

In statistics, θ, the lowercase Greek letter 'theta', is the
usual name for a (vector of) parameter(s) of some general
probability distribution. A common problem is to find the value(s)
of theta. Notice that there isn't any meaning in naming a parameter
this way. We might as well call it anything else. In fact, a lot of
distributions have parameters which are usually given other names.
For example, it is common use to name the the mean and deviation of
the normal distribution *μ* (read: 'mu') and deviation *σ
('*sigma'), respectively.

96 degrees Let theta represent the measure of the angle we are trying to find and theta' represent the measure of its supplement. From the problem, we know: theta=theta'+12 Because supplementary angles sum to 180 degrees, we also know: theta+theta'=180 Substituting the value from theta in the first equation into the second, we get: (theta'+12)+theta'=180 2*theta'+12=180 2*theta'=180-12=168 theta'=168/2=84 Substituting this value for theta' back into the first equation, we get: theta+84=180 theta=180-84=96

### What does negative sine squared plus cosine squared equal?

To determine what negative sine squared plus cosine squared is equal to, start with the primary trigonometric identity, which is based on the pythagorean theorem... sin2(theta) + cos2(theta) = 1 ... and then solve for the question... cos2(theta) = 1 - sin2(theta) 2 cos2(theta) = 1 - sin2(theta) + cos2(theta) 2 cos2(theta) - 1 = - sin2(theta) + cos2(theta)

### Can sine theta equals tan theta equals theta be equal for small angels?

Yes. (Theta in radians, and then approximately, not exactly.)

### What is csc theta?

That depends on the value of the angle, theta. csc is short for "cosecans", and is the reciprocal of the sine. That is, csc theta = 1 / sin theta.

Your question is insufficiently precise, but I'll try to answer anyway. "Sine squared theta" usually means "the value of the sine of theta, quantity squared". "Sine theta squared" usually means "the value of the sine of the quantity theta*theta". The two are not at all the same.
