Since P(-3,3) is a point on the terminal side of angle 0, we can use the unit circle to find the trigonometric values:
sin(0) = 3/√(9+9) = 3/√18
cos(0) = -3/√(9+9) = -3/√18
tan(0) = 3/(-3) = -1
csc(0) = 1/3
sec(0) = 1/-3 = -1/3
cot(0) = -1/3

explanation :
sin(0) = opposite side (3) / hypotenuse (√(9+9)) = 3/√18
cos(0) = adjacent side (-3) / hypotenuse (√(9+9)) = -3/√18
tan(0) = opposite side (3) / adjacent side (-3) = 3/(-3) = -1
csc(0) = 1 / sin(0) = 1/3
sec(0) = 1 / cos(0) = -1/3
cot(0) = 1 / tan(0) = -1/3
