Help with my post - Latex Error ....

[Math Amateur]

I have just completed a post in the Analysis Forum ... but unfortunately the post cntains a Latex eroor and I cannot determine what it is ...

The Latex expression that is the problem is \left\lvert \int_a^b \lvert \gamma^' (t) \rvert \ dt - \sum_{ k = 1 }^m \lvert \gamma^' ( \tau_k ) \rvert ( t_k - t_{ k - 1 } ) \right\rvert \lt \epsilon
It shows in the post as \displaystyle \left\lvert \int_a^b \lvert \gamma^' (t) \rvert \ dt - \sum_{ k = 1 }^m \lvert \gamma^' ( \tau_k ) \rvert ( t_k - t_{ k - 1 } ) \right\rvert \lt \epsilon Can someone please help me to find the error ...?

OK ... I solved the problem ...

I replaced \gamma^' with \gamma' ...

... ... I was just suspicious ...BUT ... what actually is wrong with \gamma^' ... ... ?Peter

In TeX, the apostrophe symbol is automatically interpreted as a superscript. If you want to use it as a super-superscript, you need to enclose it in braces. Compare \gamma' and \gamma^{'}: ${}\ \gamma' \ \gamma^{'}$.
