1.2 Approximations and round off errors

* Mathematical approx

*Computers -> Round off errors

1.2.1 - Error Definitions

True value = approx + error

Relative error:

Et = (True_Value - approx) / True_Value

Approx. relative error:

Ea = (current_approx - previous_approx) / current_approx

1.3 Truncation Errors and Taylor Series

Taylor Theorem:

f(x) = f(x*) + f´(x*)(x-x*) + (f´´(x*) / 2!) (x-x*)^2 + ... + Rn (remainder)

Rn = (f
