derivative of

63 cos (7 x)

- 441 sin (7 x)

Solution steps

\frac{d}{d x} (63 cos (7 x))

Take the constant out:

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

= 63 \frac{d}{d x} (cos (7 x))

Apply the chain rule:

- sin (7 x) \frac{d}{d x} (7 x)

= - sin (7 x) \frac{d}{d x} (7 x)

\frac{d}{d x} (7 x) = 7

= 63 (- sin (7 x) \cdot 7)

Simplify

= - 441 sin (7 x)

\frac{1}{4} x^{2} - 1, y = 8, y = 2

\int_{0}^{π} 2 sin^{4} (3 t) d t

y^{^{''}} - 5 y^{^{'}} + 4 y = 0, y (0) = 1, y^{^{'}} (0) = \frac{1}{4}

n = 4 \sum \infty 3 - 0. 5^{n}

y^{^{'}} = \frac{x}{1 + 2 y}
