cot theta=tan(90-tetha)
Tangent (theta) is defined as sine (theta) divided by cosine (theta). In a right triangle, it is also defined as opposite (Y) divided by adjacent (X).
I think you mean the concept of inverse trig functions.Let's just look at one, the inverse cosine function.cos-1 (x) also called arccos(x) is the inverse of cos(x).cos-1 (x) x=cos (theta)So to evaluate an inverse trig function we are ask what angle, theta, did we plug into the trig function (regular, not inverse function) to get x.So here is one more example.tan-1 (x) means x=cos (theta)
It also equals 13 12.
Given that theta is the angle with respect to the positive X axis of a line of length 1, then sin(theta) = Y and cos(theta) is X, with (X,Y) being the point at the end of the line. As theta sweeps from 0 to 360 degrees, or 0 to 2 pi radians, that point draws a circle of radius 1, with center at (0,0).Since X, Y, and 1 form the sides of a right triangle, where 1 is the hypotenuse, then the pythagorean theorem states that X2 + Y2 = 12. This means that sin2(theta) + cos2(theta) = 1.Tan(theta) is defined as sin(theta) divided by cos(theta), or Y / X. Since division by zero is a limiting invalidity, then tan(theta) is asymptotic to Y=0, having value of +infinity at theta = 90 or pi / 4, and -infinity at 270 or 3 pi / 4.
In a Right Triangle SINE Theta is equal to the: (Length of opposite side) / (Length of Hypotenuse).

The arc tangent is the recicple of the tangent which is also known as the cotangent. The tangent of π/2 is undefined, thus the cotangent would be zero.
The TI-83 does not have the cot button, however, if you type 1/tan( then this will work the same as the cot since cot=1/tan. The other way to do this is to type (cos(x))/(sin(x)) where x is the angle you're looking for. This works because cot=cos/sin

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

you need also an angle (theta) besides the radius. Then assuming that the starting point of both plane and Cartesian plane is the same: x=R*cos(theta), y=R*sin(theta)
The theta symbol is often associated with spirituality and represents the concept of the soul's journey and transformation. It is seen as a symbol of unity and balance, connecting the physical and spiritual realms. In some belief systems, the theta symbol is also linked to the idea of eternal life and the cyclical nature of existence.
No. Cos theta (Cos θ) is a trigonometric function. A vector is any physical quantity which has both magnitude and direction. For example, Displacement. Displacement has a magnitude like 240m or 0 or 13 m, etc. It also depends on the direction. If an object moves along the positive direction of x-axis, then the displacement will have a positive sign and if it moves along the negative direction of x-axis, then displacement will be negative. Thus, it has both direction and magnitude and so is a vector. Cos theta is a trigonometric function, strictly speaking.
