Answer:
Cos t = -4/5 and tan t = -3/4 (2nd quadrant)
Explanation
Given the trigonometry function
sin(t) = 3/5
According to trigonometry identity
sin theta = opposite/hypotenuse
This means that;
Opposite = 3
Hypotenuse = 5
Get the adjacent
hyp^2 = opp^2 + adj^2
5^2 = 3^2 + adj^2
25 = 9 + adj^2
adj^2 = 25 - 9
adj^2 = 16
adj = \sqrt{16}
adj = 4
Get Cos(t)
Cos t = adj/hyp
Cos t = 4/5
Get tan(t);
tan(t) = opp/adj
tan(t) = 3/4
Since the trig identities are in the second quadrant, this means that cost and tan t are negative. Hence Cos t = -4/5 and tan t = -3/4
Others are Cotangent t = -4/3, cosec t = 5/3 and sec t = -5/4
