integral of cos^4(7-x)sin(7-x)

\int cos^{4} (7 - x) sin (7 - x) d x

\frac{1}{5} cos^{5} (7 - x) + C

Solution steps

\int cos^{4} (7 - x) sin (7 - x) d x

Apply u-substitution

: \int - cos^{4} (u) sin (u) d u

= \int - cos^{4} (u) sin (u) d u

Take the constant out:

\int a \cdot f (x) d x = a \cdot \int f (x) d x

= - \int cos^{4} (u) sin (u) d u

Apply u-substitution

: \int - v^{4} d v

= - \int - v^{4} d v

Take the constant out:

\int a \cdot f (x) d x = a \cdot \int f (x) d x

= - (- \int v^{4} d v)

Apply the Power Rule

: \frac{v ^{5}}{5}

= - (- \frac{v ^{5}}{5})

Substitute back

= - (- \frac{cos ^{5} ( 7 - x )}{5})

Simplify

- (- \frac{cos ^{5} ( 7 - x )}{5}) : \frac{1}{5} cos^{5} (7 - x)

= \frac{1}{5} cos^{5} (7 - x)

Add a constant to the solution

= \frac{1}{5} cos^{5} (7 - x) + C

\frac{d y}{d x} = e^{3 y} sin (4 x)

n = 0 \sum \infty \frac{1}{n ^{2} + 2 n}

\int \frac{5000 x}{25 x + 1500} d x

x \to 0 lim (\frac{1}{4 x})

\frac{d}{d x} (cos (2 x + 5))
