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

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

Assuming "1" means "1 radian",

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


arctan(tan1) = 1
