Thank you pasmith, actually I didn't get comething with the dimensions:
if I have g as a vector 2x1
\nabla \nabla \mathbf{f}
will be a 2x2 matrix. In the calculus of :
\left(\left((\nabla \nabla \mathbf{f}) \cdot \frac{d\mathbf{g}}{dt}\right) \cdot
\frac{d\mathbf{g}}{dt}\right)...
Hi guys, I have this function
f(g(t)) and I have to find the second time derivative of f, is it correct the following solution?:
f''=∂f/∂g*g'=∇f*g'
f ''=∇^2f*|g'|^2+∇f*g''
where ∇^2 is the laplacian function
I'll find that the minimum distance is 0... Already have the coordinate of the point p. i have to find the minimum distance and not a point p that minimize the distance.
no is not possible. I need a closed form for my problem. actually I need to know if p is inside the intersection of the circles, I thought that a minimum distance negative can give me this information.
Hi guys I have a problem to solve, I'd like to find the minimum distance between a point and a geometric locus described in closed form, for example the intersection of two circles:
p= point coordinate
p1= center coordinate circle 1
p2=center coordinate circle 2
r1=radius of circle 1...
