Re: Prevent Equations size changing? in response to nerak102Why not place all three equations in one block, with
\begin{aligned}
9 && < && 15 && < && 16 \\
\sqrt{9} && < && \sqrt{15} && < && \sqrt16 \\
3 && < && \sqrt{15} && < &&4
\end{aligned}This should prevent the lower equations from shrienking.

Re: Prevent Equations size changing? in response to léonieThey are all in one block using \begin{aligned} etc.
I use \text to enter the text parts.
Thanks for your reply.

Re: Prevent Equations size changing? in response to nerak102Can you post the LaTeX code of the equation, please?
When I try to recreate your equation, I cannot recreate the decrease insize.

Re: Prevent Equations size changing? in response to léonieHere is a good example
\begin{aligned}\text {Differentiation of}\,x^2+3xy+4y^2=58\\
2x+3y+3x\frac{dy}{dx}+8y{dy}{dx}&=0\\
(3x+8y)\frac{dy}{dx}+2x+3y&=0\\
(3x+8y)\frac{dy}{dx}&=(2x+3y)\\
\frac{dy}{dx}&=\frac{(2x+3y)}{(3x+8y)}\\
\text{at the point}\,\,(2,\,3)\,x=2,\,y=3\quad \frac{dy}{dx}&=\frac{(4+9)}{6+24}\\
&=\frac{13}{30}\\
\text{if gradient is}\,m\,\text{gradient of normal is}\,&=\frac{1}{m}\\
\frac{1}{\frac{13}{30}}=\frac{1}{1}\div\frac{13}{30}&=\frac{1}{1}\times\fr ac{30}{13}=\frac{30}{13}\\
\text{For equation if line through}\,\,(2,\,3)\\
\frac{y3}{x2}&=\frac{30}{13}\\
13y39&=30x60\\
30x13y21&=0
\end{aligned}
