Integral of sin^4 (6x) dx

DENIUS [597]

Hello,

$\boxed{sin^4\ x= \frac{3}{8}- \frac{cos\ 2x}{2}+\frac{sin\ 4x}{8} }\\

Let's assume t=6x \ dt=6\ dx\\

 \int\limits {sin^4\ 6x} \, dx = \frac{1}{6} *\int\limits {sin^4\ t} \, dt \\

= \dfrac{1}{6} *( \frac{3t}{8} - \frac{sin\ 2t}{4} +\frac{sin\ 4t}{32})+C\\

= \dfrac{3x}{8} - \frac{sin\ 12x}{24} +\frac{sin\ 24x}{192} +C

Using substitution or elimination 9x+3y=-7 y=-3x+4

-Dominant- [34]

Answer:

No solution

Step-by-step explanation:

If we substitute the y into the equation, we get 9x+3(-3x+4)=-7

If we distribute the 3, we get 9x-9x+12=-7

This then cancels out both 9x's and we are left with 12=-7, making it no solution.
