Second Order Non Homogeneous DE
Sorry for the late reply, yes I made a bad mistake with respect to the characteristic equation . I got it now though thanks! Edit: I misunderstood the "hint" on the assignment. Every second order DE of this form, will have that solution given a single root.- utility

Second Order Non Homogeneous DE
Homework Statement Find the solution to :y''+2y'+y=t Homework Equations Suppose y(t)=B1t2+B2t+B3 And I believe, Y(t)=Yh+Yp. That is the solution is equal to the solution to the homogenous equation, plus the particular solution. The Attempt at a Solution First Solve the...- utility

Find the intervals on which a function is increasing/decreasing?
I graphed F(x) and it looked to be increasing on a certain interval, however when graphing F'(x) it is certainly negative everywhere it is defined. So it ok to say the function is decreasing everywhere it is defined?- utility

Find the intervals on which a function is increasing/decreasing?
Homework Statement F(x)=6/x-(1/1-x) Find the intervals on which the function is increasing/decreasing? Homework Equations F(x)=6/x-(1/1-x) F'(x)= -6/x^2 -1/(1-x)^2 The Attempt at a Solution Critical points are x=0 and x=1 Function has a discontinuitiy at 0...- utility
