Find the value of the number a such that the families of curves y=(x+c)−1and y=a(x+k)13 are orthogonal trajectories.
im trying to write htis on matlab to have it solved can you help me

the y=a(x+k)^1/3 thats the second y equation thats incorrect on the top
Mauricio Alvarez on 14 Sep 2020
then the first is supposed to be y=(x+c)^-1

Hi Mauricio,
As per my understanding, you intend to solve the above mentioned system of equations pertaining to the specified condition of trajectories being orthogonal. I'd suggest using the diff and solve function in MATLAB for achieving the above task.
Please refer to syms documentation also to use diff and solve.
Also refer to the below discussions on the same lines:
Thanks
