hand, if you type a :=b^2 (with a colon) then you have assigned the value b^2 (a symbol) to a variable

called a. Mupad will substitute b^2 for a any time it is used later. For example try this

Notice that a in the ‘eq1’ object has been replaced by b^2. You can clear the value of a variable using the

‘delete’ function

If you want to clear all variables, you can use the ‘reset’ function. This completely restarts mupad from

the beginning. This is often useful for starting a new homework problem.

Let’s try some more algebra

Mupad doesn’t simplify expressions by default. But it can do so if you ask it to

This sort of thing is especially handy for trigonometric functions
