Like so:
Right idea (almost!) but you have the wrong signs
\(u=\frac{-5+i\sqrt{59}}{6}\\v = \frac{-5-i\sqrt{59}}{6}\)
Integrating factor of equation (x^2+1)dy/dx+2xy=x^2-1 is
As follows:
Like so
I agree with jugoslav:
As follows (I think!):
Use the fact that tan = opposite/adjacent, so here:
tan(37º) = 72/X
Rearrange to find X.
What is the smallest distance between the origin and a point on the graph of y=1/sqrt(2) + (x^2-3)?
