In the attached file test1, two terms are to be compared using the "is" function. Theoretically, these terms are equal. A plot is provided for illustration. However, regardless of which symbol ("equal," "not equal," etc.) is used in "is," the result is always "false." What am I doing wrong?

simplify(exp(u)/(1+exp(u))^2)

exp(u)/(1+exp(u))^2

 (1)

is(exp(u)/(1+exp(u))^2 = 1/(4*cosh((1/2)*u)^2))

false

 (2)

plot([exp(u)/(1+exp(u))^2, 1/(4*cosh((1/2)*u)^2)], u)
