Firstly rearrange the differential equation to fit the form dx/dt +P(t)x = Q(t). The integrating factor is then found by using the formula:
u = EXP(INTG(P(t))). We know that P(t) = 2t and so by int...
DFS, or Depth First Search traverses a graph - which is any set of interconnected nodes 'depth first'. It tries to go all the way to the end, and if it fails returns back to the last intersection that it ...
de Moivre's: (cos(x)+isin(x))n=cos(nx)+isin(nx) set n=2 (cos(x)+isin(x))2=cos2(x)+2isin(x)cos(x)-sin2(x), which, according to de Moivre's cos2(x)+2is...
Humans have a logarithmic perception of the majority of uncountable and some countable things. A0, which is percieved as the basic note, has a frequency of 27.50 Hz. A1=55 Hz, and A<...
Despite it being frequently argued that the women in Hamlet are “drawn in fainter lines than their male counterparts,” it appears that upon closer inspection their roles are much more integral to...
