\frac{d}{d x} (x cos (t))

cos (t)

Solution steps

\frac{d}{d x} (x cos (t))

Treat

t

as a constant

Take the constant out:

(a \cdot f)^{'} = a \cdot f^{'}

= cos (t) \frac{d x}{d x}

Apply the common derivative:

\frac{d x}{d x} = 1

= cos (t) \cdot 1

Simplify

= cos (t)

\int \frac{1}{e ^{z}} d z

T \to 9 0^{\circ} lim (f (T))

\frac{\partial}{\partial x} (\frac{4}{3} π x^{3})

\frac{\partial}{\partial x} ((x^{4} + 3 x^{2}) (1 - 5 x))

y^{^{''}} - 6 y^{^{'}} + 8 y = 0, y (0) = 2, y^{^{'}} (0) = 1
