Write the complex number in rectangular form. If necessary, round to the nearest tenth 12(cos 267 i sin 267°) 12(cos 267 i sin 267°) i j, v 2i-j, and w Find the specified scalar or vector Let v be the vector from initial point Pi (-2,- 3) to terminal point P2-(6,2). Write v in terms of i and j. The vector from point Pi-(-2,-3) to point P2 6.2) is v- (Simplify your answer. Type your answer in terms ofi and j)

Explanation / Answer

1) sin 45o = a/(32)

==> a = (32)sin 45o = (32)(1/2) = 3

==> a = 3

cos 45o = c/(32)

==> c = (32)cos 45o = (32)(1/2) = 3

==> c = 3

sin 30o = a/b

==> b = a / (sin 30o)

==> b = 3/(1/2) = 6

cos 30o = d/b

==> d = b cos 30o = 6(3/2) = 33

==> d = 33
