Why bother with a post grad course - waste of time? 17-10-2016
1. Q. arctan w = 1, what is w?
2. tan x?

tan x?
No, i did that as a guess but it is wrong - w doesn't equal 45 degrees

Besides it asks for the answer to be given to 2 d.p. in the question
4. Is this in radians or degrees?

Doesn't say... it's just says

arctan x = 1 (soz it wasn't w after all)

find the value of x to 2 d.p.

All i know that it's not 45 degrees
6. Assuming "1" means "1 radian",

x = tan(1) = 1.56
7. arctan x = 1
so x = tan1 = 0.02

arctan(tan1) = 1
