Select the correct answer.
If the point (3/5, 4/5) corresponds to an angle
in the unit circle, what is tan 0
?
OA. (4)/(3)
OB. (3)/(4)
OC. (5)/(4)
OD. (5)/(3)

So, if the point is  x = 3/5  and  y = 4/5, the value of tan θ  =  (4/5) / (3/5)  =  4/3

Step-by-step explanation:

If you have a unit circle, the value of sine is the y-value, the value of cosine is the x-value, and the value of tangent is y/x.

f(x) = x^3 -2x^2 -3x

x( x^2 -2x-3)

x( x^2 +x -3x -3)

x( x(x+1) -3(x+1))

x( x-3)( x+1)

so zeroes are 0, 3,-1
