(dr)/(dθ)+rtan(θ)=3tan(θ)

\frac{d r}{d θ} + r tan (θ) = 3 tan (θ)

r (θ) = c_{1} cos (θ) + 3

Solution steps

\frac{d r}{d θ} + r tan (θ) = 3 tan (θ)

Solve separable ODE:

r (θ) = c_{1} cos (θ) + 3

r (θ) = c_{1} cos (θ) + 3

e^{5} + ln (7)

\int \frac{1}{3 x + 4} d x

y^{^{'}} + x y = a

\frac{d}{d x} (- 3 x^{5})

\frac{d}{d y} (ln (x^{4} + y^{4}))
