This can be seen when SOLVE displays the following eqn taken from "Sound Waves":
"'(as(cm/(s^2)))=-((ω(r/s))/(1_r))^2(scm)' "
The negative sign appears inside the square operation. This is an obvious error because what is depicted and calculated is an eqn with the wrong factor which is (-(ω(r/s))/(1_r))^2(s_cm).
The same occurs in "Simple Harmonic" for the 3rd eqn:
"'(a(m/s^2))=-(ω0(r/s))^2/(1_r)^2(xm_m)COS((ω0_(r/s))*(ts)+(φ°))' "
