Differential Equations PLEASE!

It seems that you didn't multiply tan(x) with the -cos(x) term.

It seems that you didn't multiply tan(x) with the -cos(x) term.

i turned tan(x) into sinx/cosx and canceled out the cosx, and was left with

-sin^2 x + cos^2 x + sinx + sin^2 x -cosx = cos^2 x

any ideas?

Like I said, you wrote:

-sin^2 x + cos^2 x +sinx +[tan x] sinxcosx -cosx = cos^2x

When it should be:

-sin^2 x + cos^2 x +sinx +[tan x]( sinxcosx -cosx) = cos^2x

When it should be:

-sin^2 x + cos^2 x +sinx +[tan x]( sinxcosx -cosx) = cos^2x

aww, such a simple mistake, thanks a lot :)
