The Attempt at a Solution

Hello
As you see my solution I found TM(5 , 2.5) that is incorrect because n should be integer not float number.In Addition when I check book solution I found TM mode is TM(2,1)
what is my mistake?

Hi baby_1,

Have you checked the errata for the edition of the book you are using. Seems to me there is a typo in their problem statement (which doesn't even tell you what units to use for the coordinates [itex]x[/itex] and [itex]y[/itex]. What textbook is this from?

Cheers,
Gabba
