Question

Evaluate (if possible) the six trigonometric functions of the real number. (If not possible, enter IMPOSSIBLE.)
t = 5π/6

Answer 1

sint = 1/2

cost = -sqrt(3)/2

tant = -1/sqrt(3)

csct = 2

sect = -2/sqrt(3)

cott = -sqrt(3)

Answer 2

work out sine and cos from graph, then

tan = sin/cos

csc = 1/sin

sec = 1/cos

cot = 1/tan

Answer 3

cost = -sqrt(3)/2 is this \[\sqrt{-3}/2\]

Answer 4

\[\cos(t) = -\frac{\sqrt{3}}{2}\]

Answer 5

the negative is outside

Answer 6

if you remember how to convert radians to degrees, then know the standard values for 0, 30 , 60 , 45, 90 , 180 its really useful.
