Latex’s mathematical formula: derivation and representation of fraction

Representation method

: fractional representation
: partial derivative sign
: normal derivative D (orthomorphic)

code effect meaning

x

y

\frac{x}{y}

YX

score

\partial

partial derivative symbol

d

t

\mathrm{d}t

DT

derivative

give an example

$$
\frac{\partial y}{\partial x_1} + \frac{\partial y}{\partial x_2} \\
\frac{\mathrm{d}y}{\mathrm{d}x_1} + \frac{\mathrm{d}y}{\mathrm{d}x_2}
$$

The display effect is as follows:
0

y

x

one

+

y

x

two

\frac{\partial y}{\partial x_ 1} + \frac{\partial y}{\partial x_ 2}

∂x1​∂y​+∂x2​∂y​
