How did I get this question wrong

When you pulled

2\tan \theta

out it should have been

2\tan \theta(1-2\tan^2 \theta)

and not

2\tan \theta(1-4\tan^2 \theta)

Also, moved to maths.

In the future, please try and post your threads in the maths forum. I've had to move a ton of your threads there over the past week or so.
