To begin, let's learn to use Python as a calculator, with the arithmetic operations, the addition, the subtraction, the multiplication, the power and the division.

Launch Anaconda in Spyder and follow me! The simpler way to use Python as a calculator is to directly write on the console. For instance, 2 + 4, and you obtain 6.

2 - 4 is -2,

2 times 4 is 8,

2 to the power 4 is 16,

and 2 divided by 4 is 0.5.

You can also use variables.

You type x equals 2, then the variable x is 2.

y equals 4, the variable y is 4

and z is x plus y.

And if you want to show z, you type print z, and you obtain 6.

Another way to do it is to make a new file in the editor.

Then to save it and then you type into it.

x equals 2.

You have to use variables in the script.

y equals 4.

z equals x plus y.

And print z.

Then you save: File, save.

And then you run: run run.

And you obtain six in the console.

What's coming now? What's coming now are the trigonometric functions, with NumPy package.
