how can I simplify the following equation in MATLAB?

363980279322033920/3639802793220339 - (363980279322033920*exp(-2750*t)*(cosh((2^(1/2)*12600542294779661^(1/2)*t)/65536) + (90112000*2^(1/2)*12600542294779661^(1/2)*sinh((2^(1/2)*12600542294779661^(1/2)*t)/65536))/12600542294779661))/3639802793220339

Eqn = 363980279322033920/3639802793220339 - (363980279322033920*exp(-2750*t)*(cosh((2^(1/2)*12600542294779661^(1/2)*t)/65536) + (90112000*2^(1/2)*12600542294779661^(1/2)*sinh((2^(1/2)*12600542294779661^(1/2)*t)/65536))/12600542294779661))/3639802793220339;
Result = vpa(simplify(Eqn, 'steps',10), 7)

Result =
100.0*exp(-2750.0*t)*(0.06764003*exp(-2422.31*t) - 1.06764*exp(2422.31*t)) + 100.0
