Question

In Video lecture 05 round about 37' where Pr. Jerison draws the f(x)=tan(x) and f(x)=arctan(x) the two curve crosses where if I plug in real data I can't get the same results, did he lowered the curve to just to illustrate the symmetry along the y=x line or do you have to do some kind of stretch to get the same picture?

Answer 1

both are inverse function.........so they are symmetric to line y=x

Answer 2

Thanks, that bit I get, what I'm not sure about is that does the graph of tanx and arctanx overlap or not.

Answer 3

yes they meet at y=x=1

Answer 4

So do you know what I could do to get the same graph as in the video where the two curves cross each other?

Answer 5

no, u cant draw that graps....because we are not accurate. But u can roughly sketch it

Answer 6

I have quick graph on my iPhone and the two graphs never cross that's why I'm asking :-)
