If we replace y with x2cos x and solve for y', we can conclude that the derivative is

marusya05 [52]

Y = x^2 cos x

y' = x^2 * -sin x + cos x * 2x

= 2x cos x - x^2 sin x

= x ( 2 cos x - x sin x)

Subject differential equation Day. Month. Year. .. (y-secx ) dx + tanxdy...o

Colt1911 [192]

$(y-\sec x)\,\mathrm dx+\tan x\,\mathrm dy=0$

Divide both side by $\mathrm dx$ and rearrange terms to get a linear ODE;

$\tan x\dfrac{\mathrm dy}{\mathrm dx}+y=\sec x$

Multiply both sides by $\cos x$ :

$\sin x\dfrac{\mathrm dy}{\mathrm dx}+\cos x\,y=1$

The left side can be condensed as the derivative of a product:

$\dfrac{\mathrm d}{\mathrm dx}(\sin x\,y)=1$

Integrate both sides, then solve for $y$ :

$\sin x\,y=x+C\implies\boxed{y(x)=x\csc x+C\csc x}$
