Answer:

$\frac{ {tan}^{2} x}{2} + \ln( |cos \: x| ) + C$

Step-by-step explanation:

$\int {tan}^{3} x \: dx$

$\int \: tan \: x \times {tan}^{2} x \: dx$

$\int \: tan \: x( {sec}^{2} x - 1) \: dx$

distribute

$\int \: tan \: x \: {sec}^{2} x - tan \: x \: dx$

$\int \: tan \: x \: {sec}^{2} x \: dx \: - \int \: tan \: x \: dx$

$\int \: tan \: x \: {sec}^{2} x \: dx \: - \int \frac{sin \: x}{cos \: x} \: dx$

First integrand

let tan x = u

du = sec²x dx

Second integrand

let cos x = z

dz = -sin x dx

$= \int u \: du \: - \int - \frac{1}{z} dz$

$= \frac{ {u}^{2} }{2} + \ln( |z| ) + C$

$= \color{red}{ \boxed{ \frac{ {tan}^{2} x}{2} + \ln( |cos \: x| ) + C}}$

What is the missing coefficient?

Afina-wow [57]

For this case we have the following expression:

$(15x ^ 2 + 11y ^ 2 + 8x) - (7x ^ 2 + 5y ^ 2 + 2x) =$

We eliminate the parentheses taking into account that:

$- * + = -\\15x ^ 2 + 11y ^ 2 + 8x-7x ^ 2-5y ^ 2-2x$

We add similar terms:

$15x ^ 2-7x ^ 2 + 11y ^ 2-5y ^ 2 + 8x-2x =$

Different signs are subtracted and the sign of the major is placed:

$8x ^ 2 + 6y ^ 2 + 6x$

Finally, the expression is reduced to:

$8x ^ 2 + 6y ^ 2 + 6x$

Answer:

$8x ^ 2 + 6y ^ 2 + 6x$
