Problem 10. (1 point) Evaluate the following expressions. Your answer must be an angle in radians and in the interval [-,, ,, . To enter an answer involving 7, write 'pi', e.g., as in 'pi/7'. (a) sin (-}) = (b) sin ' (0) = (c) sin 1(V2) =Problem 8. {1 point} 1 Suppose the point I: 9. 2) is on the graph of y = g(.l?) What point must be on the graph of y = g (1.1 ? 1 J ' . help (points) The point must be on the graph of y = g (1.1 Problem 9. (1 point) Suppose we have a right triangle with legs of length a and b and hypotenuse of length c. Suppose b = 3 and c = 5. Then a= If A is the angle across from the side of length a, then tan(A)
