What does the mean of product of two orthogonal matrix is orthogonal in terms of rotation?
The mean of the product of two orthogonal matrices, which represent rotations, is itself an orthogonal matrix. This is because the product of two orthogonal matrices is orthogonal, preserving the property that the rows (or columns) remain orthonormal. When averaging these rotations, the resulting matrix maintains orthogonality, indicating that the averaged transformation still represents a valid rotation in the same vector space. Thus, the mean of the rotations captures a new rotation that is also orthogonal.
What else can I help you with?
Prove that the product of two orthogonal matrices is orthogonal and so is the inverse of an orthogonal matrix What does this mean in terms of rotations?
To prove that the product of two orthogonal matrices ( A ) and ( B ) is orthogonal, we can show that ( (AB)^T(AB) = B^TA^TA = B^T I B = I ), which confirms that ( AB ) is orthogonal. Similarly, the inverse of an orthogonal matrix ( A ) is ( A^{-1} = A^T ), and thus ( (A^{-1})^T A^{-1} = AA^T = I ), proving that ( A^{-1} ) is also orthogonal. In terms of rotations, this means that the combination of two rotations (represented by orthogonal matrices) results in another rotation, and that rotating back (inverting) maintains orthogonality, preserving the geometric properties of rotations in space.
How do you name the direction of a vector?
The direction of a vector is defined in terms of its components along a set of orthogonal vectors (the coordinate axes).
What does rotation mean in math terms?
turning
In mathematics terms what is the definition of degree?
A degree is a measure of rotation, with 360 degrees representing a complete rotation returning to the starting point.
How many terms does the product of the sum and difference of two terms have?
7 terms

How can the rotation matrix be expressed in terms of spherical coordinates?
The rotation matrix can be expressed in terms of spherical coordinates by using the azimuthal angle (), the polar angle (), and the radial distance (r) to determine the orientation of the rotation.
How do you name the direction of a vector?
The direction of a vector is defined in terms of its components along a set of orthogonal vectors (the coordinate axes).
How do you enter the matrix?
You have to hack into the Matrix. In simple terms, you use WiFi to trick the Matrix into thinking you are just a regular person still hooked in.

You can solve a system of equations by translating it into a matrix manipulating the matrix until it has eliminated terms and then translating it back to equations?
True
Why sin and cos terms are only used for representing a signal?
That is just not true. Sin and cos terms are used for many other purposes : for example the components of a force along orthogonal axes.
What does rotation mean in medical terms?
In medical terms, as in lay language, rotation means turning around an axis. The common uses in medical/anatomical terms are to describe movement at a joint (for instance, rotation of the neck is the movement you use when you shake your head "no." External rotation at the shoulder is what you use when you scratch the back of your neck.) Also, rotation might describe a malposition of an organ -- for instance, a slightly twisted uterus rotated left might be called levorotated (and to the right, dextrorotated.)

The terms strategic behavior and payoff matrix both relate directly to?

What is smallest degree of rotation for a circle?
The smallest degree of rotation for a circle is 0 degrees, which represents no rotation at all. However, in terms of practical movement, any infinitesimally small angle, such as 0.0001 degrees, could also be considered the smallest measurable degree of rotation. In mathematical terms, a circle can be rotated by any angle, no matter how small.
