SOLUTION: (cos x -sin x)^n
(sin x cos x)
=
(cos(nx) -sin(nx))
(sin(nx) cos(nx))
Show that for all natural numbers n. Using formulas for cosine and sine.
(those are suppose to b
Question 26589: (cos x -sin x)^n
(sin x cos x)
=
(cos(nx) -sin(nx))
(sin(nx) cos(nx))
Show that for all natural numbers n. Using formulas for cosine and sine.
(those are suppose to be matrix and the x in the matrix are suppose to be pheta)
