[sympy] solving for Euler angles

Hello, I'm learning Sympy and trying to replicate a solution for the Euler pitch and roll angles as described in a well-known Application Note: https://cache.freescale.com/files/sensors/doc/app_note/AN3461.pdf In particular, Equations 24 through 26. Here's the set up matching the reference fram

[sympy] latex print system of equations

Hello, I cannot find the proper sympy incantation so that the following system of equations (sy is my alias for sympy: >>> sy.Eq(omega_e, euler_rates, evaluate=False) Eq(Matrix([ [ \dot\phi], [\dot\theta], [ \dot\psi]]), Matrix([ [\omega_x + \omega_y*sin(\phi)*tan(\theta) + \omega_z*cos(\phi)*

[sympy] factoring matrix

Hello, I'm trying to work out the derivation of the relationship between Euler angle rates in terms of Euler angles and angular rates in body frame (e.g. http://dma.ing.uniroma1.it/users/lss_da/MATERIALE/Textbook.pdf section 1.2.2). I have developed this for the so-called "Tait-Bryant" rotation a
