How Find \cos{(\pi A)} if A is Orthogonal matrix
https://math.stackexchange.com/questions/605159/how-find-cos-pi-a-if-a-is-orthogonal-matrix
I'm afraid the equation \cos (\pi A) = E - 2A, \tag{1} where A is an orthogonal matrix, cannot hold, at least in the stated generality. To see a counterexample, consider the matrix J = \begin{bmatrix} 0 & -1 \\ 1 & 0 \end{bmatrix}, \tag{2} ...
What is \cos(\frac{\pi t}{2^n}) in terms of \cos(\pi t)?
https://math.stackexchange.com/q/2829065
Writing \cos(\pi t) in terms of \cos(\frac{\pi t}{2^n}) ... the same thing as writing \cos(2^n\theta) in terms of \cos(\theta) ... is a Chebyshev polynomial
What is the value of \displaystyle{\cos{{\left(-\pi\right)}}} ?
https://socratic.org/questions/what-is-the-value-of-cos-pi
\displaystyle{\cos{{\left(-\pi\right)}}}=-{1} Explanation: Consider a definition of a function \displaystyle{\cos{{\left(\theta\right)}}} on a unit circle as an abscissa (X-coordinate) of a ...
How do you evaluate \displaystyle{\cos{{3}}}\pi ?
https://socratic.org/questions/how-do-you-evaluate-cos-3pi
Gió May 5, 2015 You can consider it visually as a graph and remember the periodicity of your \displaystyle{\cos} , meaning that it repeats itself at regular intervals (oscillating ...
How do you find the exact value of \displaystyle{\cos{{5}}}\pi ?
https://socratic.org/questions/how-do-you-find-the-exact-value-of-cos-5pi
1 Explanation: Unit circle --> \displaystyle{\cos{{\left({5}\pi\right)}}}={\cos{{\left(\pi+{4}\pi\right)}}}={\cos{\pi}}=-{1}
How do you evaluate \displaystyle{\cos{{8}}}{\left(\pi\right)} ?
https://socratic.org/questions/how-do-you-evaluate-cos-8-pi
\displaystyle{1} Explanation: Notice that one complete rotation is \displaystyle{2}\pi : So \displaystyle{8}\pi is just 4 complete rotations. We therefore only need to find: \displaystyle{\cos{{\left({0}\right)}}} ...
