Do not ignore error messages! Your equation example \documentclass{article} \usepackage{amsmath} \begin{document} \begin{equation} |\varphi_p(t)-\varphi_p(t_0)|=|0_3.t_1(k^{t_2}t_3) ...(k^\epsilon\tau_{2n+1}...-0_3.t_1(k^{t_2}} t_3)...(k^\epsilon t_{2n+1}..| \leq|k^\epsilon \tau_{2n+1}-k^\epsilon t_{2n+1}|/3^{n+1} + |k^{\epsilon+\tau_{2n+...

Here is a simple way to achieve this: \documentclass{article} \usepackage{amsmath,amstext} \usepackage{newtxmath} \begin{document} \begin{equation} \begin{cases} \displaystyle \nu(z_0)+\frac{g}{f}\frac{\partial\,\eta_s}{\partial\,x} =\frac{g}{f}\frac{\partial\,\eta}{\partial\,x}\\[15pt] \displaystyle\text{with }\nu(z_0) = \frac{1}{f\rho_0}\frac{\partial\,...

I would do it this way, using the dcases and rcases environment from mathtools. Also, the esdiff package simplifies typing (partial) derivatives. \documentclass{article} \usepackage{mathtools} \usepackage{fourier, erewhon} \usepackage{esdiff} \begin{document} \begin{equation} \begin{rcases}\begin{dcases} ν(z₀)+\frac{g}{f}\diffp{\eta_s}{x} =\...

Using amsmath \documentclass{article} \usepackage{amsmath} \begin{document} If you want it center-aligned inside the braces, use \texttt{gathered} \begin{equation} \left\{ \begin{gathered} v(z_0) + \frac{g}{f} \frac{\partial\eta_s}{\partial x} = \frac{g}{f} \frac{\partial \eta}{\partial x} \\ \text{with } v(z_0) = \frac{...

After some guessing how your equation should looks, I obtain: MWE for above picture is: \documentclass{report} \usepackage{mathtools} \begin{document} \begin{align} \mathcal{H}_{q1} & \mathcal{H}_{q2} \mathcal{H}_{q3} \dots \mathcal{H}_{qn}0 \notag \\ & =\frac{1}{2}H_{q1}\{\mathcal{H}_{q2}\mathcal{H}_{q3} \dots \mathcal{H}_{qn}...

\documentclass{article} \usepackage{amsmath} \usepackage{array} \begin{document} \[ \begin{array}{llllll} x^2 & x^3 & x^4 & x^5 & x^6 & x^7 \\ f''(x)=2 & f'''(x)=6 & f''''(x)=24 & f'''''(x)=120 & f''''''(x)=720 & f'''''''(x)=5040 \end{array} \] \end{document}

You haven't provided any alignment points, so I've had to make a few educated guesses as to where you want them to be. Maybe something like the following is what you're after? If I've mis-guessed, please do clarify what you're after. \documentclass{article} \usepackage{amsmath} % for 'align' environment \usepackage[margin=2.5cm]{geometry} % set text ...

Well, this should serve as starting point how to rewrite your code manually. Conversion from Word is really awful and not usable ... I repeat the firs equation row three times and left second and third row to rewrite and given example of the first line to you: \documentclass{article} \usepackage{mathtools} \begin{document} \[ X(n )= \begin{dcases} ...

I dont know whether this is what you are looking for: \documentclass{article} \usepackage{geometry} \usepackage{amsmath,amstext} \usepackage{newtxmath} \begin{document} \def\mult{\times} \begin{equation} X(n) = \begin{cases} \left[\frac{y}{1-y\mult\left(r\mod\frac{1}{y}\right)}\right] \left[\left(\alpha\mult\left(\frac{F_{\mathit{current}}}{F_{\mathit{...

Still simpler with mathtools. I added a command for old style derivatives: \documentclass{article} \usepackage{fourier, erewhon} \usepackage{textcomp} \usepackage{geometry}% \usepackage{mathtools} \newcommand\osder[2]{#2^{\textsc{\scriptsize(\romannumeral #1)}}} \begin{document} \[ \begin{matrix*}[l] x^2 & x^3 & x^4 & x^5 & x^6 & x^...

In the 2nd invocation, I use roman numerals to denote higher-order derivatives, which is a common style I have seen. \documentclass{article} \usepackage{stackengine} \renewcommand\stackalignment{l} \renewcommand\stacktype{L} \setstackgap{L}{1.2\baselineskip} \stackMath \begin{document} \[ \stackunder{x^2}{f''(x)=2}\quad \stackunder{x^3}{f'''(x)=6}\quad \...
