Answer:

sin^2α

Step-by-step explanation:

I will just pose x instead of alpha here to make things simpler

$\tan ^2\left(x\right)\left(2\cos ^2\left(x\right)+\sin ^2\left(x\right)-1\right)\\\\$

we know that sin^2x = 1 - cos^2x so...

$=\left(-1+1-\cos ^2\left(x\right)+2\cos ^2\left(x\right)\right)\tan ^2\left(x\right)$

$=\cos ^2\left(x\right)\tan ^2\left(x\right)$

we can rewrite using trigonometric identities (tan = sin/cos)...

$=\left(\frac{\sin \left(x\right)}{\cos \left(x\right)}\right)^2\cos ^2\left(x\right)\\= \sin ^2\left(x\right)$

If $x(t)=k$ is constant, then $\dfrac{\mathrm dx}{\mathrm dt}=0$ , so you have

$5k-3=0\implies k=\dfrac35$
