1. >> y = 2^2+log(pi)*sin(4) y = 3.1337
2. >> theta = acos(-1) theta = 3.1416
3. >> format long >> theta theta = 3.141592653589793
>> format short >> theta theta = 3.1416
>> format short e >> theta theta = 3.1416e+00
4.1 >> (2^5)/(2^5)-1 ans = 0
>> (1 - (1/(2^5)))^(-1) ans = 1.0323
4.2 >> 3*((sqrt(5) - 1)/(sqrt(5)+1)^2)-1 ans = -6.4590e-01
4.3 >> r = (pi)^(1/3) r = 1.4646
4.4 >> exp(3) ans = 20.0855
>> log(exp(5)) ans = 5
>> log10(exp(4)) ans = 1.7372
>> log10(10^5) ans = 5
4.5 >> exp((pi)*sqrt(163)) ans = 2.6254e+17
4.6 >> sin(pi/6) ans = 0.5000
>> cos(pi) ans = -1
>> tan(pi) ans = -1.2246e-16
4.7 >> (sin(pi/6))^2 + (cos(pi/6))^2 ans = 1
4.8 >> (1+3i)/(1-3i) ans = -0.8000 + 0.6000i
4.9 >> exp(i*(pi/4)) ans = 0.7071 + 0.7071i
>> cos(pi/4)+i*(sin(pi/4)) ans = 0.7071 + 0.7071i
Se cumple la igualdad en ambas ecuaciones.
4.10 >> exp(pi/2*i) ans = 0.0000 + 1.0000i
>> exp(pi/2i) ans = 0.0000 - 1.0000i
No hay ninguna diferencia entre ambas ecuaciones, porque un número y una literal juntos,
aunque no tengan el signo de multiplicación, si lo representan.
