implicit (dy)/(dx),xy=7

implicit derivative

\frac{d y}{d x}, x y = 7

\frac{d y}{d x} = - \frac{y}{x}

Solution steps

x y = 7

Treat

y

y (x)

Differentiate both sides:

y + x \frac{d y}{d x} = 0

Isolate

\frac{d y}{d x} : \frac{d y}{d x} = - \frac{y}{x}

\frac{d y}{d x} = - \frac{y}{x}

\int \frac{2 x ^{2}}{x ^{2} - 1} d x

\frac{d y}{d x} = e^{4 x} + 9 y

\int 2 x^{4} e^{x^{5}} d x

t an g e n t f (x) = x^{2} + 6, at x = - 7

\int_{- 2}^{- 1} cos (n \cdot \frac{π}{2} \cdot x) d x
