Compute The Following In Matlab: Y= Cosh^2(X) - Sinh^2(X) , X= 32* Pi

Hello, I have the Equation

Y= Cosh^2(X) - Sinh^2(X) , X= 32* Pi

How can i solve it in MATLAB

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])
