Answer:
sin, cos, sec, csc
Step-by-step explanation:
If the terminal side passes through (-1, -1), the angle θ = 225° and is in the third quadrant.
sinθ = opp/hyp = -/+ = -
cosθ = adj/hyp = -/+ = -
tanθ = opp/adj = -/- = +
cotθ = adj/opp = -/- = +
secθ = 1/cosθ = -
cscθ = 1/sinθ = -
The functions that will be negative for the angle are sin, cos, sec, and csc.
