1. ### one-parameter family of solutions

How do I "guess" a one-parameter family of solutions to the differential equation y' = (2y)/t?
2. ### one-parameter family of solutions

find the one-parameter family of solutions for each of the following differential equations dy/dx = x/y dy/dx = [ (e^y)*(sin x)^2 ] / [ y*(sec x) ] dy/dt + y = cos (e^t)
3. ### one-parameter weibull distribution

i need to find the E[x] and E[x^2] for the one-dimential weibull distribution. the pdf is given by: 2ax*e^(-ax^2), where a is the parameter i can only integrate it by introducing the erf function. and i cant find anything online about thie one-parameter case thanks :)
4. ### one-parameter family of conics

Hi to everybody!!!! I have to find a solution to these problems, but i'm not able. The question are: 1.What is the general formula for the one parameter family of conics through the points (1,1), (1,-1), (-1,-1), (-1,1). I hope someone can help me! Thank you very much. 2. Suppose...
