New issue 4000 by [email protected]: Geometric Algebra - gradient of an
exponential
http://code.google.com/p/sympy/issues/detail?id=4000
Hi team,
With git version of sympy (to be the 0.7.4 release), I don't understand the
following results for the attached script :
my exponential = exp(-E*gamma_w*t)
-E*gamma_w*exp( -E*gamma_w*t )*gamma_t = E*exp(-E*gamma_w*t)*gamma_t^gamma_w
grad*(my exponential) = -E*gamma_w*exp(-E*gamma_w*t)*gamma_t
grad*(my exponential)+E*gamma_w*(my exponential)*gamma_t =
-E*gamma_w*exp(-E*gamma_w*t)*gamma_t - E*exp(-E*gamma_w*t)*gamma_t^gamma_w
Is it a correct value for the gradient ?
