Question

Evaluate the function f(x)=tan^-1(x) when x=0. Give your answer in radians.

Answer 1

The answer is equal to 0.

Answer 2

Answer:

The value of the given function f(x) at x = 0 is 0

Step-by-step explanation:

The function is given to be :

$f(x)=\tan^{-1}x$

Now, we need to find the value of the given function f(x) when x = 0

So, To find f(0) we substitute x = 0 in the given function f(x)

$\implies f(x)=\tan^{-1}x\\\\\implies f(0)=\tan^{-1}(0)\\\\\implies f(0)=\tan^{-1}(\tan 0)\\\\\implies f(0)=\tan^{-1}\tan(0)\\\\\implies f(0)=0$

Therefore, The value of the given function f(x) at x = 0 is 0
