7. Consider the ordered bases B = (sin(3x), cos(3x), sin (3x), cos (3x), sin(3x) cos(3x)) and C = (1. cos(6z). sin(6z), cos(3z), sin(3z)) for a subspace W of C (R). (a) Find the transition matrix from B-coordinates to C-coordinates. (Hint: While this problem can be done using row reduction, it is easier, in- stead, to consider various trig identities that you learned in calculus.) (b) Use your answer to part (a) to express f(x) = sin(3x) (1 - 2 sin(3x) + 5 cos(3x)) in C-coordinates.

Transcribed Image Text:7. Consider the ordered bases
B = (sin(3x), cos(3x), sin (3x), cos (32), sin(32) cos(3x))
and
C = (1, cos(6x), sin(6x), cos(3x), sin(3x))
for a subspace W of C (R).
(a) Find the transition matrix from B-coordinates to C-coordinates. (Hint:
While this problem can be done using row reduction, it is easier, in-
stead, to consider various trig identities that you learned in calculus.)
(b) Use your answer to part (a) to express
f (x) = sin(3x) (1 – 2 sin(3x) + 5 cos(3x))
in C-coordinates.
