Ran in:
I think you probably want to ask "Why does the hyperbolic trigonometric identity behave anomalously?" Especially when ...
x = 5*pi:0.00000001*pi:6*pi;
cosh2x = exp(-2*x)/4 + exp(2*x)/4 + 1/2;
sinh2x = exp(-2*x)/4 + exp(2*x)/4 - 1/2;
y = cosh2x - sinh2x;

plot(x/pi, y), grid on, ylim([-0.5 2.5])
subplot(212)
plot(x/pi, y), grid on, ylim([-0.5 2.5]), xlim([5.957161 5.9571615])
