(\partial)/(\partial u)(u^2+v^2)

\frac{\partial}{\partial u} (u^{2} + v^{2})

2 u

Solution steps

\frac{\partial}{\partial u} (u^{2} + v^{2})

Treat

v

as a constant

Apply the Sum/Difference Rule:

(f \pm g)^{'} = f^{'} \pm g^{'}

= \frac{\partial}{\partial u} (u^{2}) + \frac{\partial}{\partial u} (v^{2})

\frac{\partial}{\partial u} (u^{2}) = 2 u

\frac{\partial}{\partial u} (v^{2}) = 0

= 2 u + 0

Simplify

= 2 u

\int \frac{8 x}{1 - 4 x ^{2}} d x

f (x) = e^{1 + 2 t a n (x)}, at x = \frac{π}{4}

t \cdot sin (k \cdot t)

3 x^{2} \frac{d y}{d x} = 2 x^{2} + y^{2}

x \to - 4 lim (- 5 x - 8)
