-sin^2(x)/cos(x) tycker jag borde bli -tan(x)-sin(x), men jag ser inte vad det på riktigt, men jag är säker på att det är double angle identity:

[math]\begin{align*} \sin x\cos x &=\left(\frac{e^{ix}-e^{-ix}}{2i}\right)\left(\frac{e^{ix}+e^{-ix}}2\right)\\ &=\frac{(e^{ix}-e^{-ix})(e^{ix}+e^{-ix})}{4i}\\ &

As it is there are many possible answers. One is just: sinx/cosx +cosx/sinx = sinx/cosx +cosx/sinx. dub-star. 1 find an identity for sinx find an identity for tanx.
