Usage

Image format (svg or png)

Normal

<img src="https://math.giainhanh.vn/img?from=\log\prod^N_{i}x_{i}=\sum^N_i\log{x_i}" />

Inline

<img src="https://math.giainhanh.vn/img?inline=\log\prod^N_{i}x_{i}=\sum^N_i\log{x_i}" />

Mathml format

curl https://math.giainhanh.vn/mathml?from=\log\prod^N_{i}x_{i}=\sum^N_i\log{x_i}

Option

.svg or .png extension

URL ends with .svg extension will be treated as a normal math formula.

Some Markdown blog services won't treat image tags correctly whose URL has no any image extension in it. This option may give fixes to these situations.

<img src="https://math.giainhanh.vn/img?from=\log\prod^N_{i}x_{i}=\sum^N_i\log{x_i}.png" />

Optional input format type

Math-api support latex, asciimath and mathml

<img src="https://math.giainhanh.vn/img?from=root(4)(x)&type=asciimath" />

Output format type:

• svg
• png
• mathml
