Solving the Capacitor Equation
For a particular capacitor/battery set up, we have the following values
Ti=37, Ta=254 (in volts)
and we have determined that the relationship between time t (in seconds) and voltage
(in volts) when the capacitor charges is g

Investigating Memory States
In this question, we want to examine how the state of memory changes. When Maple evaluates an
expression or equation, it uses the current values assigned to the variables.
We want to execute a series of Maple commands in

Solving with Pressure and Temperature
For a particular gas in a chemical system, the pressure P (measured in kilopascals) is related to
temperature s (measured in degrees Celsius) by the relationship described in Maple notation as
P := (s) -> alpha

Trig Functions using Degrees
The Trigonometric functions built into Maple use radians as a measure of angles. In many fields, degrees
is preferred over radians when performing calculations. We can use Maple to create our own
trigonometric functions
