I'll start with some piss easy vectors shit...
Show that
[eqn] r=(2,1,0) + λ(-1,2,4) [/eqn]
And
[eqn] r=(-1,3,2) + μ(2,-5,3) [/eqn]
are perpendicular
Someone... Anyone?

Just a crumb of help. I am a mere spec seeking just a few bytes online to guide me in the most miniscule way.
Please offer me your help amidst the countless math you deal with daily. I will be beyond grateful

Whether they are perpendicular will depend on the value of lambda and mu. But in general, any two vectors are perpendicular if their dot product is 0. Also, don't name both vectors r, that shit is confusing, they're not the same vector.

Calculate the scalar product as a function of lambda and mu. Then show that the function fulfils what it needs to fulfill for the vectors being perpendicular.
Are you people really that fucking stupid. It's two lines you fucking mongoloids
How can I prove that every von Neumann natural numbers model element that's not an empty set is a successor?
Would it be sufficient to note that every element that's not an empty set is a composition of successions on the empty set and hence the given element must be too?
We dont know your homework. For all we know, one of the variables was given in class, or theres a visual representation you need or theres a specific process required by the professor to solve the problem.
Dot the second terms with each other. Is the dot product zero? Is it zero for all values of lambda, mu?

No, we're really that unwilling to do your homework for you.
Anyone good at Matlab in here?
I cam up with some equations that describe the acceleration, velocity, and displacement of a rocket with no other forces acting on it, I'd like to show all three of those on a single graph, however the three results are all orders of magnitude apart so one of the plot will end up shit. I've managed to make 2 axes on my graph so it looks good for two of the plot but does anyone how I can have the same graph with 3 axes, one for each data set?

/sqt/ has been around for a long time.
Its helpful to a lot of people and is a containment thread for all hw related stuff.
I see no wrong in this.Neither should you.
Also questions are totally /sci/ related.

Just realised I may as well use sub plot, nevermind
