The purpose of reporting issues with a product to r&d is to improve the product. Checking a result against other sources is normal engineering practice.
Your question seems to imply you would be happy with this result:
((e^(1/2*τ))^2*(e^(i/2*τ))^2*tan(τ/4)^2+(e^(1/2*τ))^2*(e^(i/2*τ))^2+(-1-i)*(e^(1/2*τ))^2*e^(i/2*τ)*tan(τ/4)^2+(2+2*i)*(e^(1/2*τ))^2*e^(i/2*τ)*tan(τ/4)+(1+i)*(e^(1/2*τ))^2*e^(i/2*τ)+(−i)*(e^(1/2*τ))^2*tan(τ/4)^2+(−i)*(e^(1/2*τ))^2+i*(e^(i/2*τ))^2*tan(τ/4)^2+i*(e^(i/2*τ))^2+(1+i)*e^(i/2*τ)*tan(τ/4)^2+(2+2*i)*e^(i/2*τ)*tan(τ/4)+(-1-i)*e^(i/2*τ)-tan(τ/4)^2-1)/((2+2*i)*e^(1/2*τ)*e^(i/2*τ)*tan(τ/4)^2+(2+2*i)*e^(1/2*τ)*e^(i/2*τ))
Do you prefer the challenge of finding commands that unlock the hidden answer..just curious?

Did you try
lin(trig2exp(...))
?
