Review the idea of reference angles, which are always in QI.
sin 0.0135 = 0.0135
That is the angle in QI.
But sin is negative in QIII and QIV. So we have
π+0.0135 and 2π-0.0135
cot 0.351 = 2.731
But, cot is negative in QII and QIV, so we have
π-0.351 and 2π-0.351
Approximate, to the nearest 0.01 radian, all angles theta in the interval [0,2pi) that satisfy the equation.
a.) sin theta=-0.0135
b.) cot theta=-2.731
Thank you for helping! I appreciate it!
