@@mantask.9688 I don't think their current power source could support 2 lasers. They need to research a better power source before doing so. I think a rail gun that shoots like a shotgun is a good counter to the boomerangs. I think the ship shoots a plasma bolt like a star wars laser. A real laser would be invisible to us and we'd only see the turret turning and boomerangs exploding. Not sure why the kangaroos never bothered to invest in multi warhead boomerangs that split up with decoy boomerangs released.

6:52 for anyone who was confused a derivative is the slope of its function at 2 points so infinitely close together they form one point. The reason a derivative’s x-intercepts coincide with peaks and valleys of it’s parent function is because a line perpendicular to the peak of the parent function has a slope of 0, or a horizontal line.

[@Weezytrout101]

Genuinely curious; you state that a general equation for solving for the unknown variable (t) only exists in polynomials that have 4 or less degrees. Why did you reduce your 6th degree polynomial all the way down to the first degree? Why not settle for those general equations of the 2-4th degrees? Additionally, is it quicker to reduce it all the way down to the first degree or is it computationally quicker to not take the derivative 5 times?

[@b2stud]

its definitely possible to stop at the 4th degree or the 3rd even, but those formulas are extremely long. The 4th degree equation has around 100 instances of its coefficients in it, just for one x-intercept...

[@b2stud]

it might be quicker than reducing to the 1st degree, but it's very easy to get the formulas wrong

once you find the x-intercept of the line, you can use that to solve the quadratic, then you can use those x-intercepts to solve the cubic and so on until you solve the original line. The original line's x-intercepts are what you want to find.
