Find the values of the six trigonometric functions for ∠A in standard position determined by the point (63, 280). Enter your answers as fractions.
sin A
cos A
tan A
csc A
sec A
cot A

clearly your point is in the first quadrant, so all trig ratios will be positive.
from (63,280)
x = 63, y = 280
r^2 = x^2 + y^2 = 63^2+280^2 = 82930
r = √82930
You should know the trig ratios in terms of
x, y and r
e.g.
tan A = y/x = 280/63 = 40/9
sec A = r/x = √82930/63
etc.
