LaTeXコマンド:積分と重積分

積分はintで表します。

積分

\int_{a+1}^{b-1}f(x)dx

latex_integral_1

カッコと半角スペースの相性を調べました。

\int_a^b f(x) dx \
\int_a^b f(x)dx \
\int_a^bf(x)dx \
\int_a+1^b f(x) dx \
\int_a^b+1 f(x) dx \

latex_integral_2

重積分

\int\int_{S}f(x,y)dxdy

latex_integral_3

intをそのまま重ねると空白ができる。\!を2〜3個つけるとちょうどいい形になる。

\int\int_{S}f(x,y)dxdy \
\int!\int_{S}f(x,y)dxdy \
\int!!\int_{S}f(x,y)dxdy \
\int!!!\int_{S}f(x,y)dxdy \

latex_integral_4

積分はintで表します。重積分はintをそのまま重ねると空白ができる。!を2〜3個つけるとちょうどいい形になる。
