cant really tell what your after; applied force? or just motion of rotation about the origin?

Domain of x: [-length of cannon, length of cannon]

well i want to make this cannon rotate over a origin ^^
amistre64
  • amistre64
x = |cannon| cos(t) y = |cannon| sin(t)
anonymous
  • anonymous
just thouht that I can use trigonometry to make it rotate
anonymous
  • anonymous
hmmm then what we do to rotate?
amistre64
  • amistre64
you can use parametric equations to make it rotate
anonymous
  • anonymous
hmm
anonymous
  • anonymous
i think that if we ++ sint that can rotate
anonymous

becuase hypotenuse is const and the if we raise the averse edge we can make hypotenuse move ^^
anonymous
  • anonymous
and to raise the averse edge we should raise the sint ye?

var g = setInterval('rotateMe',speed) function rotateMe() { x = |length| Math.cos(t) y = |length| Math.sin(t) plot = 'position:absolute; top:y; left:x' document.getElementById('img').position = plot t = t+angle of rotation {

hmmm give me a min to analyse this

WOW really good!

so make 2 dats and draw the cannon between these 2 dats?
amistre64
  • amistre64
yep
anonymous
  • anonymous
one of them is origgn .. and the other one is the end of hypotenuse

really nice! I just started to program this in C# and XNA :D

its been awhile since i played in vb; prolly would have to take a refresher course
anonymous
  • anonymous
VB u mean Visual baisc .NET?
anonymous
  • anonymous
well why you need a refresher course?

gonna be taking a few programming courses for my math degree, nothing to fancy lol

AHh k ^^ can you explain me what is nmemonic devices?
amistre64
  • amistre64
it means memory trick. Something that is supposed to help you remember how to perform something.
anonymous
  • anonymous
hmmm kk
amistre64
  • amistre64
pedmas is a mnemonic device for remembering the order of operations
anonymous
  • anonymous
hmm ty

so how can we use these?
