Find all solutions of the equation in the interval \( [0,2 \pi) \). \( -\cot x-1=\csc x \) Write your answer(s) in radians in terms of \( \pi \). If there is more than one solution, separate them with commas. \( x=\square \)

Consider the line \( y=-\frac{1}{2} x+8 \) What is the slope of a line perpendicular to this line? What is the slope of a line parallel to this line? Slope of a perpendicular line: Slope of a parallel line:

Find all solutions of the equation in the interval \( [0,2 \pi) \). \[ \cot ^{2} x+2 \csc x=-1 \] Write your answer in radians in terms of \( \pi \). If there is more than one solution, separate them with commas. \( x=\square \)

\( \left. \begin{array} { l } { \lim _ { x \rightarrow 3 } \frac { x ^ { 2 } - 9 } { x ^ { 2 } - 5 x + 6 } } \\ { \lim _ { x \rightarrow 3 } \frac { \sqrt { x + 1 } - 2 } { x - 3 } } \\ { 2,2 / 8 } \\ { 3 _ { 2 } / 2 / 3 } \end{array} \right. \)

Use long division to divide. \[ \left(x^{3}-3 x^{2}-18 x+6\right) \div(x-2) \]
