Calculus

I have recently been given the following question but I have no idea how to differntiate the equation or plot the equations. Can you please help me?

Capacitor = 100 nF

Resistor = 47 kΩ

Supply voltage = 5 V

Charging characteristic for a series capacitive circuit:

v=V(1- e-^(1/T)) where T=CR

n Use a spreadsheet to plot the charging curve over the range 0 to 20 ms (milliseconds).

n Differentiate the charging equation and find the rate of change of voltage at 6 ms.
