integral of cos^7(x)tan^6(x)

\int cos^{7} (x) tan^{6} (x) d x

\frac{sin ^{7} ( x )}{7} + C

Solution steps

\int cos^{7} (x) tan^{6} (x) d x

Rewrite using trig identities

= \int sin^{6} (x) cos (x) d x

Apply u-substitution

: \int u^{6} d u

= \int u^{6} d u

Apply the Power Rule

: \frac{u ^{7}}{7}

= \frac{u ^{7}}{7}

Substitute back

u = sin (x)

= \frac{sin ^{7} ( x )}{7}

Add a constant to the solution

= \frac{sin ^{7} ( x )}{7} + C

\int (8 - 4 x) e^{2 x} d x

\frac{d y}{d x} - 4 tan (2 x) y = sin (2 x)

x \to 0 - lim (e^{c s c (x)})

n = 1 \sum \infty \frac{e ^{\frac{7}{n}}}{n}

\frac{d}{d x} (p x + b)
