How can I find the points of intersection of cosh(x) and sec(x)?
Plotting the two, I can see that it has a root around 4.7, but then I can't tell where the next root is.
But when I use
FindRoot with a guess of 4.7 I don't get the root but if I use a guess between 4.72 and 4.8 then I find the root - 4.730040744862704.
Also, another root - 7.8532046241 can be found by guessing between 7.83 and 7.85.
Q: Is there a better way to solve the equation:
Q: How do I see the other points of intersection of the graphs
Any help would be much appreciated. Thanks!
