If P (x, y) is the point on the unit circle determined by the real number θ, then tan θ=
x/y
y/x
1/x
1/y
If P(x, y) is the point on the unit circle determined by the real number θ, then the correct expression for tangent (tan) of θ is:
x / y
To find the value of tan θ, we need to consider that for a point (x, y) on the unit circle, x is the cosine value and y is the sine value of the angle θ. In this case, since P(x, y) is a point on the unit circle, x and y represent the cosine and sine values respectively.
Therefore, tan θ can be calculated as y/x.
So, the correct option is y/x.
