Hi Puys,
Lets create a repository of formulas/shorcuts.
Let me inaugurate with this blessing related to Time,Speed and Distance
When objects are starting simultaneously from a point on a circular track with speeds being 'n' times that of the first object :
speed of object 1 = x
object 2=2x
object 3= 3x....and so on
then they meet at exactly m-1 points at intervals of 1/(m-1) *total distance
Happy meal from Numbers:
when (x^m) *(y^n) is constant,the minimum value of ax+by is realized when
(ax/m)=(by/n)
Whereas,
when ax+by is constant the maximum value of (x^m) *(y^n) is realized when (ax/m)=(by/n)
Some of the basic ones,easily forgotten,
Distance between 2 parallel lines ax+by+c1=0
and ax+by+c2=0
is c1-c2/sqrt(a^2 +b^2)
