%i have this coupler matrix in parametric form

syms t

coupler_parametric=[5163136522924301/2251799813685248, 2^(1/2)/2 - (8*t)/(t^2 + 1), - (4*(t^2 - 1))/(t^2 + 1) - 2];

i want to find magnitude of this matrix in terms of t

please someone help

But i think that there is mistake in calculating square of this term and adding 5163136522924301/2251799813685248.

What is your basis for distrusting the calculation?

see 5163136522924301/2251799813685248 this number is greater than 1 ,so its square should be greater than 1 which i thought by seeing the output square which seems less than 1,which i misunderstood.

Thanks for your answer!!
