Differential equation question, 4th derivative of y + y = 0
Ok, see, that was my entire question how did they get plus or minus \pm\frac{1}{\sqrt{2}}\pm \frac{1}{\sqrt{2}}i ??- Pr0x1mo

Differential equation question, 4th derivative of y + y = 0
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...- Pr0x1mo

Differential equation question, 4th derivative of y + y = 0
Yes it does, which is the reason why wolfram alpha spat out the general solution using cos + sin (bernouilli).- Pr0x1mo

Differential equation question, 4th derivative of y + y = 0
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...- Pr0x1mo

Differential Equation problem, I think i solved it, just need it to be check
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'...- Pr0x1mo

Calculate the flow rate of the etching solution
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...- Pr0x1mo

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)...- Pr0x1mo
