The reason i know that there are i's in the solution is because this question came from the chapter in my book titled "Characteristic equations and complex roots," did you take a look at the solution that wolframalpha displayed? I know that this is the answer because my Professor alluded to...
Ok, the question/equation is
y^4 + y = 0
Now i know that the characteristic equation is m^4 + 1 = 0
and if i would to solve that it would give me plus or minus 1i as a complex root. so the general solution would be:
c1cos(x) + c2sin(x) but i know this is not the answer because...
My teacher gave me this as an extra credit question:
solve: (x+y)dx-(x-y)dy=0
I first used the substitution of y=vx or v=y/x
Taking the partial derivative of y = vx yields:
dy/dx = v + x(dv/dx)
So then i rearranged the equation like: dy/dx = (x+y)/(x-y) which equals:
v + xv'...
Well, Si is the limiting reagent I'm assuming.
and If CH3CO2H is 100% i can set that to CH3CO2H 100 mols and using the stoichemetric ratios, i get:
CH3CO2H 100 mols
Si 52.5 mols
HNO3 70 mols
HF 49 mols
H2SiF6 52.5 mol
NO 70 mol
H2O 140 mol
From here, where does the specific...
Homework Statement
In the semiconductor industry, integrated circuit (IC) production begins with the mechanical
slicing of silicon rods into wafers. Once the wafers are sliced, the surfaces are lapped and
polished to uniform flat surfaces. Contaminants and microscopic defects (work damage)...
