Find the Derivative - d/dx y=2tan(x)

- \frac{d}{d x} y = 2 tan (x)

y = 2 ln (cos (x)) + c_{1}

Solution steps

- \frac{d y}{d x} = 2 tan (x)

Isolate

y^{'} (x) : y^{'} (x) = - 2 tan (x)

f^{^{'}} (x) = g (x)

then

f (x) = \int g (x) d x

y = \int - 2 tan (x) d x

\int - 2 tan (x) d x = 2 ln (cos (x)) + c_{1}

y = 2 ln (cos (x)) + c_{1}

- \frac{d}{d x} (4 sin (x))

- \frac{d}{d x} (sin (x y))

\frac{d y}{d x} y = sin (x)

- \frac{d}{d x} (4)

- \frac{d}{d x} (csc (2 x))
