Please type your questions. I don't think anyone will want to help you this way.

Ok, i remember, i thought it was another question ^^

For the problem : there's something disturbing me : the condition of applying the formula is that tan(x)=tan(x+a)

If you take a=pi/3, tan(x) is not = to tan(x+pi/3)

(i wonder how you typed it...) - Mar 23rd 2008, 03:50 AMmr fantastic
in the first line

"given: ...."

there's a typo. The first = obviously should be a multiplication.

Your answer and the books answer do NOT appear to be exactly equivalent. Your answer looks more correct. The book appears less correct. This is the problem when part of the answer has been rounded to a certain decimal approximation (in the case of the book, 1 decimal place) .... - Mar 23rd 2008, 05:32 AMafeasfaerw23231233
oh no, sorry! i

i make a typo mistake. It should be tan x tan (x +a )= k - Mar 23rd 2008, 05:41 AMmr fantastic
