Given


f(x)=\tan x

To fill the blanks.

Now,

The grpah of f(x)=tanx is given as,

Therefore, from the graph,


\tan x=\tan (x+\pi)=\tan (x+2\pi)

Then,


\pi\text{ is the fundamental period of tanx.}

Also,

For x=0, tan(0)=0.

Therefore, the y-intercept is (0,0).

The points for the function f(x)=tanx is,


\begin{gathered} x=(\pi)/(3),\text{ y=tan(}(\pi)/(3))=\sqrt[]{3} \\ x=(\pi)/(4),y=\tan (\pi)/(4)=1 \end{gathered}

Since


\tan (-A)=-\tan A

Then, the points of the graph y=tanx is,


(-(\pi)/(3),-\sqrt[]{3}),(-(\pi)/(4),-1),(0,0),((\pi)/(3),\sqrt[]{3}),((\pi)/(4),1)

Hence, the answer should be in the order,

i)


\pi

ii)


(0,0)

iii)


(-(\pi)/(3),-\sqrt[]{3}),(-(\pi)/(4),-1),(0,0),((\pi)/(3),\sqrt[]{3}),((\pi)/(4),1)
