\frac{d}{d x} (x^{2} sin (π x))

2 x sin (π x) + cos (π x) π x^{2}

Solution steps

\frac{d}{d x} (x^{2} sin (π x))

Apply the Product Rule:

(f \cdot g)^{'} = f^{'} \cdot g + f \cdot g^{'}

f = x^{2}, g = sin (π x)

= \frac{d}{d x} (x^{2}) sin (π x) + \frac{d}{d x} (sin (π x)) x^{2}

\frac{d}{d x} (x^{2}) = 2 x

\frac{d}{d x} (sin (π x)) = cos (π x) π

= 2 x sin (π x) + cos (π x) π x^{2}

\frac{d y}{d x} = y sec^{2} (x)

\int 8 x e^{0.5 x^{2}} d x

3 y^{^{''}} + 108 y = 0

\frac{\partial}{\partial x} ((x - y) (x y - 1))

\frac{d}{d x} (\frac{x \cdot sin ( x )}{1 + cos ( x )})
