format of equation coefficients

Please, I have a part of a script transcript:

Btheta=miz*Htheta; Btheta=subs(Btheta) format shortEng Btheta

The output doesn't present Btheta with the specified format:

Btheta =

(17802902220170337*sin(12*theta)*(107143972736275332039373393850264279320385678996161089849618843107/(294922159623673235357688878068056260995678776047895991812096000000000000000000000000000000000000000*r^12) - (191800976967353723011910915374755859375*r^12)/121976946326485916357963791565979648))/1180591620717411303424

How can I format the coeffients?

Thanks in advance.

Use the vpa function.
