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.
There is no particular meaning associated with theta - it will depend on the context.
'Theta' is a zero-looking Greek letter with a line across. It is used in physics and many mathematic equasions.
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 means 't' or 'th' and sigma means 's'.
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.
Lots of alpha-theta brain wave activity mean that you are relaxed. This is because alpha-theta brain activity occurs during the sleep cycle.
"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.
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… Read More
If you really want to know, ask a member of Iota Phi Theta Fraternity, Inc.
Absolutely none of your business unless you are a member of Theta Chi. In which case, you should know who to ask. Its actually the genus name of a rattle snake, which is the mascot of Theta Chi.
In Physics and equations of motion, double dot is the same thing as the second derivative- theta double dot = theta'' and so forth.

theta means u and any ways no such thing
tan2(theta) + 5*tan(theta) = 0 => tan(theta)*[tan(theta) + 5] = 0=> tan(theta) = 0 or tan(theta) = -5 If tan(theta) = 0 then tan(theta) + cot(theta) is not defined. If tan(theta) = -5 then tan(theta) + cot(theta) = -5 - 1/5 = -5.2
How would you solve and show work for cos2 theta if cos squared theta equals 1 and theta is in the 4th quadrant?
cos2(theta) = 1 cos2(theta) + sin2(theta) = 1 so sin2(theta) = 0 cos(2*theta) = cos2(theta) - sin2(theta) = 1 - 0 = 1
Mean particle size=0.94*Lambda/(FWHM*cos(theta)
The only real solution is theta = 0 For theta < 0 square root of 3 theta is not defined. For theta > 0, sin theta increases slower than 3*theta and so the sum is always negative. The only real solution is theta = 0 For theta < 0 square root of 3 theta is not defined. For theta > 0, sin theta increases slower than 3*theta and so the sum is always negative. The… Read More
How do you solve theta if cos squared theta equals 1 and 0 is less than or equal to theta which is less than 2pi?
cos2(theta) = 1 so cos(theta) = Â±1 cos(theta) = -1 => theta = pi cos(theta) = 1 => theta = 0
The abbreviation TTBOD stands for ........Something you will find out if you ever become a member of Delta Sigma Theta Sorority, Inc. Please respect that.
There are three of them. Granted this means that there are different variations of all three. I'll show you the variations as well. This is coming straight from my Math 1060 (Trigonometry) notebook. Sorry there is no key to represent the angle; Theta. 1. Sin2 (of Theta) + Cos2 (of Theta)= 1 Variations: Sin2 (of Theta) = 1- Cos2 (of Theta) AND: Cos2 (of Theta) = 1-Sin2 (of Theta) 2. Tan2 (of Theta) + 1… Read More
Cotan(theta) is the reciprocal of the tan(theta). So, cot(theta) = 1/2.
it is the formula for magnetic field strength by Amankwah -Yeboah
They are thirsty and your should get them a drink.
For such simplifications, it is usually convenient to convert any trigonometric function that is not sine or cosine, into sine or cosine. In this case, you have: sin theta / sec theta = sin theta / (1/cos theta) = sin theta cos theta.
the mean is important in statistics because you will find out your average and can compare that mean to other things..
Since sin(theta) = 1/cosec(theta) the first two terms simply camcel out and you are left with 1 divided by tan(theta), which is cot(theta).
tan (theta x theta) : must square the value of the angle, theta, before applying the trig function, tangent.
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
In statistics, this is the symbol for the "Variance"
If sine theta is 0.28, then theta is 16.26 degrees. Cosine 2 theta, then, is 0.8432
Tan theta is a function of the number theta.
It is cotangent(theta).
The derivative of (sin (theta))^.5 is (cos(theta))/(2sin(theta))
4*cos2(theta) = 1 cos2(theta) = 1/4 cos(theta) = sqrt(1/4) = Â±1/2 Now cos(theta) = 1/2 => theta = 60 + 360k or theta = 300 + 360k while Now cos(theta) = -1/2 => theta = 120 + 360k or theta = 240 + 360k where k is an integer.
Mean is the average.
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)
Cos theta squared
It is a non-linear function of theta.
It is -sqrt(1 + cot^2 theta)
-1 < sine(theta) < 1 so sine(theta) cannot be 3125
Since secant theta is the same as 1 / cosine theta, the answer is any values for which cosine theta is zero, for example, pi/2.
Since theta is in the second quadrant, sin(theta) is positive. sin2(theta) = 1 - cos2(theta) = 0.803 So sin(theta) = +sqrt(0.803) = 0.896.
Yes. (Theta in radians, and then approximately, not exactly.)
cosine (90- theta) = sine (theta)
(Sin theta + cos theta)^n= sin n theta + cos n 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.
You must not be a soror, so you don't need to know.
Given tan Theta equals negative 15 divided by 8 and 90 degrees is less than or equal to theta which is less than or equals to 180 state 5 other trigonometric ratios and determine the measure of theta?
sin(theta) = 15/17, cosec(theta) = 17/15 cos(theta) = -8/17, sec(theta) = -17/8 cotan(theta) = -8/15 theta = 2.0608 radians.
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.
