Dear List,
Please tell me if this is not the right place to ask this but I've run
into a problem using maxima.
I have an expression (code below) involving a number of trigonometric
functions. Now, I want to simplify this expression assuming certain
variables are zero. This is, I want to assume that EL_1 and AZ_1 are
zero. This would imply that my expression can be simplified as sin(0)=0
and cos(0)=1. However, calling various simplification functions on sigma
will not result in this (trivial) simplification.
What am I missing? Typing sin(EL_1); will result in 0.
Best, Dieter
sigma: sin(EL_1) * sin(EL_2) + cos(EL_1) * cos(EL_2) * cos(abs(AZ_1-AZ_2));
EL_1:0;AZ_1:0
