could somebody please help me with equation ?
i think ive just made a stupid mistake because its not working T.T
Write general solution
tan2x = cot x
tan 2x = 2tanx/(1-tansquaredx)
therefore
2tanx/(1-tansquaredx) = 1/tanx
2tansquared x = 1/2
tan squared x = 1/4
tan x = + or - 1/2
which doesnt work
and the answers say the solution is npi + or - (pi/6)
thanks for any help !!
