Enter Greek Symbols - Maple Help
For the best experience, we recommend viewing online help using Google Chrome or Microsoft Edge.

Typing Greek Symbols in Maple

 • To enter Greek symbols into in your Maple document, use the Greek palette. This works in both Text mode and Math mode.

 For details on palettes in Maple, see worksheet/expressions/palettes.
 • In math mode, you can also enter Greek symbols using Command and Symbol Completion.  See worksheet/expressions/completecommand for more information.

Using the SYMBOL Font in Plot Commands

 • To use Greek letters in a plot command, for instance to label the axes, set the appropriate font option to SYMBOL.  Then, when you enter a letter, the corresponding Greek letter is used.  For example, enter "r" for "rho", and $\mathrm{\rho }$ is displayed.
 The following is a list of corresponding Greek symbols.

 Type Symbol Name Symbol a alpha $\mathrm{\alpha }$ b beta $\mathrm{\beta }$ c chi $\mathrm{\chi }$ d delta $\mathrm{\delta }$ e varepsilon $\mathrm{ϵ}$ f phi $\mathrm{\phi }$ g gamma $\mathrm{\gamma }$ h eta $\mathrm{\eta }$ i iota $\mathrm{\iota }$ j varphi $\mathrm{\varphi }$ k kappa $\mathrm{\kappa }$ l lambda $\mathrm{\lambda }$ m mu $\mathrm{\mu }$ n nu $\mathrm{\nu }$ o omicron $\mathrm{ο}$ p pi $\mathrm{\pi }$ q theta $\mathrm{\theta }$ r rho $\mathrm{\rho }$ s sigma $\mathrm{\sigma }$ t tau $\mathrm{\tau }$ u upsilon $\mathrm{\upsilon }$ v varpi $\mathrm{\varpi }$ w omega $\mathrm{\omega }$ x xi $\mathrm{\xi }$ y psi $\mathrm{\psi }$ z zeta $\mathrm{\zeta }$ A Alpha $\mathrm{Α}$ B Beta $\mathrm{Β}$ C Chi $\mathrm{Χ}$ D Delta $\mathrm{\Delta }$ E Epsilon $\mathrm{Ε}$ F Phi $\mathrm{\Phi }$ G Gamma $\mathrm{\Gamma }$ H Eta $\mathrm{Η}$ I Iota $\mathrm{Ι}$ J vartheta $\mathrm{\vartheta }$ K Kappa $\mathrm{Κ}$ L Lambda $\mathrm{\Lambda }$ M Mu $\mathrm{Μ}$ N Nu $\mathrm{Ν}$ O Omicron $\mathrm{Ο}$ P Pi $\mathrm{\Pi }$ Q Theta $\mathrm{\Theta }$ R Rho $\mathrm{Ρ}$ S Sigma $\mathrm{\Sigma }$ T Tau $\mathrm{Τ}$ U Upsilon $\mathrm{\Upsilon }$ V varsigma $\mathrm{\varsigma }$ W Omega $\mathrm{\Omega }$ X Xi $\mathrm{\Xi }$ Y Psi $\mathrm{\Psi }$ Z Zeta $\mathrm{Ζ}$

 In this example, we set the label font for the plot to SYMBOL and label the axes $\mathrm{\rho }$ and $\mathrm{\Psi }\left(\mathrm{\rho }\right)$.
 > plot(sin(r), r=0..3, labels=["r", "Y(r)"], labelfont=[SYMBOL]);
 • You can also use typeset math in a plot command to enter 2-D math, including Greek symbols, anywhere in a plot where text is allowed.  See plot/typesetting for details.
