Question

the point (-3/5, y) in the third quadrant corresponds to angle θ on the unit circle. what is the value of sec θ

Answer 1

unit circle means
x^2+y^2=1^2=1
x^2+y^2=1

Answer 2

we have (-3/5,y) this point on circle
can u tell me the value of y after we put x=-3/5 in above equation??

Answer 3

(-3/5)^2+y^2=1
from here calculate y
from here 2 values of y will come but we will consider value with negative side bcoozz in 3rd quad y is negative

Answer 4

you had x and y now calculate sec theta

Answer 5

use property of right angle triangle now ..and try ..u will surely get a ans
