8 Find the terminal point xy on the unit circle determined b

8. Find the terminal point (x,y) on the unit circle determined by the real number 4 4t Find the domain of the function g (r) =

Solution

Reference angle is /4 and that point on the unit circle is ((2)/2, (2)/2)

This angle is in Quadrant II, where x-coordinate is negative and y is positive..so the point is (-(2)/2, (2)/2).

Answer: (-(2)/2, (2)/2)

2)

g(t) = 4t/(5 - t)^1/3

Domain ======> t < 5 or t > 5
