1.) Use a calculator to find the value of each expression rounded to two decimal places.
cot^-1 (-8.1)
2.) Write each trigonometric expression as an algebraic expression in u.
sin (cot^-1 u)
3.) Solve each expression on the interval 0 less than or equal to theta less than 2pi. Same for #4
sin (3theta + pi/18) = 1
4.) cos^2theta - sin^2theta + sin theta = 0
