comment Symbolically solve and Plot equation involving Tan
Thanks for taking the time to show how it can be solved symbolically, really appreciated.

Beautiful explanation, thank you very much I've learned a lot from this post. I just need to try and follow the simplification of the equation from my original to the one used here now for completeness.

This really is a thing of beauty, it's going to take me a while to unpick the maths behind it though.... thanks for posting.

comment How to clear variables in a manipulate without enabling dynamic content?
That's really useful, I think I'm going to have to go and read up a lot more on the use of Dynamic if I'm to make the most of the Manipulate routines. How complex would it be to add the Show command back in to introduce a straight line which connects through the solutions of the FindRoot? I've tried to do this myself by prefixing the Plot line with Show[ and then add a Graphics line to cycle through the points before TrackedSymbols, but it gives errors so I'm assuming my syntax must be off, or it needs special treatment with the Dynamic wrapper?

Additional code posted to show the effect of adding a plot function after the Manipulate appears to cause the Manipulate to enter a strange loop.

@AlbertRetey thanks for the comment, even with fixed variables or having the variables defined the graph crashes as soon as the nSeg slider is incremented, which is strange as nothing for the plot range of f[x] is updated.

That's an interesting way of getting round the Clear function, and it works well for the symbolic aspect, but if you were to add a Plot function near the end so that it was to draw the graph of the curve, as you increment the nSeg value the graphing element crashes, where if you Remove or Clear the x variable this doesn't happen, but I can't understand why. I added this line just above the nSeg call for the manipulate. Show[Plot[f[x], {x, x[1], x[nSeg + 1]}]],

comment How to clear variables in a manipulate without enabling dynamic content?
Thanks for the link, I've already been through that thread and the problem seems to be clearing variables within the Manipulate command. I've been through and simplified my code removing the subscripts and I still get the same problem unfortunately so perhaps it's not just limited to subscripted variables but clearing variables generally...

revised How do I split up a curve into segments of equal length?
Additional upper and lower values added to the FindRoot routine to prevent solutions being provided greater than upVal
