Thanks sir, same answer as me. But not sure why different from ans key...
What was the given answer like? Did it involve angles like "2x"?
Hi Eric, the answer in the ans key is 2 tan x - x + C
My guess is that the person who came up with the solutions rushed a little and wrote down
2 (tan x - x) + x + c
instead of
2 (tan x - x) + tan x + c.
2 (tan x - x) + x + c
instead of
2 (tan x - x) + tan x + c.
Yup sounds like the case, thanks Eric!
