Question

in the second quadrant of a unit circle, sin=1/3, what is sec=?

Answer 1

sin = opposite side / hypotenuse

sin = 1 /3

opposite side / hypotenuse = 1 / 3

opposite side = 1

hypotenuse = 3

Answer 2

adjacent side = x

opposite side = y

hypotenuse = h

x^2 + y^2 = h^2

x^2 + (1)^2 = (3)^2

x^2 + 1 = 9

x^2 = 8

x = sqrt(8)

sec = hypotenuse / adjacent

sec = 3 / sqrt(8)

sec = 3sqrt(8) / 8

sec = 3 2sqrt(2) / 8

sec = 3sqrt(2)/4

Answer 3

Since this is in the second quadrant, your adjacent side should be flipped.

So adjacent will have a negative value, and

sec = -3sqrt(2)/4

Answer 4

THANKS! and the sec would be?

Answer 5

*tan

Answer 6

tan = opposite / adjacent

Answer 7

Thanks!!!!!
