Eπ 2 i exp((sym(pi)/2 If any form of S contains complex values, the simplifier disfavors the forms where complex values appear inside subexpressions In case of nested subexpressions, the deeper the complex value appears inside an expression, the least preference this form of an expression getsThe decimal expansion of Gelfond's constant begins e π ≈ {\displaystyle e^ {\pi }\approx \dotsTaking the natural log again we see this is true iff lnπ > 1 lnlnπ To show this, consider the function f(x) = lnx − 1 − lnlnx Then f ′ (x) = 1 x − 1 xlnx This derivative is continuous for x > 0 and has one zero at x = e It is easy to see that f ′ < 0 for x < e and f ′ > 0 for x > e, so x = e is a minimum

Value of e^2π
Value of e^2π-Let's calculate this value mathematically To calculate the value of i, we will need to understand Euler's formula first According to Euler's formula, e ix = cosx isinx At x = π/2 x = π /2 cis x = cos π/2 i sin π/2 Here, cis x is just a notation Cis x = i So, ii = (cis π/2)i ii = e i 2 π/2 ii = eπ/2 i i =07 approximatelyValues to obtain a given desired behavior It is further desired that the engineer gain insight sufficient to design the system, often including synthesizing a new circuit, adding elements fa = f0 e– π/2≈f 0/ 481 fb = f0 eπ/2≈481 f 0 (22) A simpler choice, which better approximates the actual curve, is fa = f0 /10 fb=10f0 (23
