Solve the equations to the nearest tenth and use the given restrictions.

Question

2. sin theta = -0.204, for 90 degs < theta < 270 degs

Ans: 191.8 degs?

Answer 1

sin A = -0.204
A = -11.8o = 11.8o W. of S. = 258.2o CCW
from + X-axis.

Answer 2

Correction: If Sin A = -0.204
A = -11.8o = 11.8o N. of W. = 168.2o CCW
from + x-axis; Q2.

If Sin A = 0.204
A = 11.8o S. of W. = 191.8o CCW from +
x-axis.
