Graph using Maple for Astronomy

Click For Summary
SUMMARY

The discussion focuses on using Maple software to plot the change in Earth's equilibrium temperature based on varying albedo values from 0.3 to 0.7 in increments of 0.1. The user encountered issues with variable assignments, where Maple incorrectly recognized assigned variables as unknowns. The relevant equation for this task is L(1-a)R^2/4d^2, which needs to be properly implemented in Maple to generate the desired plot.

PREREQUISITES
  • Familiarity with Maple software for mathematical plotting
  • Understanding of the concept of albedo in climate science
  • Knowledge of equilibrium temperature calculations
  • Basic proficiency in using mathematical equations for plotting
NEXT STEPS
  • Learn how to properly assign variables in Maple software
  • Research the implementation of plotting functions in Maple
  • Study the effects of albedo on Earth's temperature using climate models
  • Explore Maple's documentation on handling equations and plotting
USEFUL FOR

Astronomy students, climate scientists, and anyone interested in using Maple for mathematical modeling and plotting related to environmental science.

Homework Statement



I am not sure what to do with Maple. I've barely used it at all, but trying to figure out why this won't work with what I have below.

Plot schematically the change in equilibrium temperature of Earth, if its albedo changes from 0.3 to 0.7 (in 0.1 jumps).

Homework Equations



[itex]\frac{L(1-a)R^2}{4d^2}[/itex]

The Attempt at a Solution



(This assignment is old btw, just wanted to figure out what I did wrong.)

When I right click on the equation and select plot it assigns my already assigned variables as unknowns between -5 and 5. Really not sure what to do?

Did I improperly assign the variables or perhaps the function?

Probably a simple Maple syntax error(hopefully). Help?
