(dr)/(dθ)+rtan(θ)=tan(θ)

Lösung

\frac{d r}{d θ} + r tan (θ) = tan (θ)

r = c_{1} cos (θ) + 1

Schritte zur Lösung

\frac{d r}{d θ} + r tan (θ) = tan (θ)

Solve separable ODE:

r = c_{1} cos (θ) + 1

r = c_{1} cos (θ) + 1

2 (sin (t) y^{^{'}} + cos (t) y) = cos (t) sin^{3} (t)

d er i v a t i v e f (x) = e^{x^{4}}

d er i v a t i v e f (x) = 3 + 5 sin (x)
