Answer:
No. The reciprocal of a function is rarely the same as the inverse of the function.
Step-by-step explanation:
tan^1(a) signifies the arctangent function, the function that returns the angle for a given tangent value of a.
tan(a)^-1 signifies the reciprocal of the tangent function, which is the definition of the cotangent function.
The attached graph compares the two functions.
It is given in the question that, PA is a radius and AB is the tangent segment .
And in a circle, radius and tangent are always perpendicular, it means they form 90 degree with each other . Or angle PAB is a right angle .
And we cant say anything about the length s of PA and AB, neither of PA and PB.
So out of the four options, correct option is the third option .
The equation is y^2=16x and the directrix is x=-4
