(dr)/(dθ)+rtan(θ)=sec(θ)

解

\frac{d r}{d θ} + r tan (θ) = sec (θ)

解

r = \frac{tan ( θ )}{sec ( θ )} + \frac{c _{1}}{sec ( θ )}

解答ステップ

\frac{d r}{d θ} + r tan (θ) = sec (θ)

線形 ODE を解く:

r = \frac{tan ( θ )}{sec ( θ )} + \frac{c _{1}}{sec ( θ )}

r = \frac{tan ( θ )}{sec ( θ )} + \frac{c _{1}}{sec ( θ )}

f(x)=6sin(x)-4xcos(x)-x^2sin(x)

f (x) = 6 sin (x) - 4 x cos (x) - x^{2} sin (x)

(\partial)/(\partial y)(50y+3000-100x)

\frac{\partial}{\partial y} (50 y + 3000 - 100 x)

(\partial)/(\partial x)((59)/((1+x^2+y^2)))

\frac{\partial}{\partial x} (\frac{59}{( 1 + x ^{2} + y ^{2} )})
