I have a conducted trigonometric manupulations to solve the geometry relations of a mechanism. For this purpose, i use a lot the FullSimplify function. This function makes for me very good simplifications. But, this function is very long. My code lasts 45 min. This is thus not all convenient to work of it.
A idea is to store the expressions which result from the simplifications so that i needn't to reevaluate it each time.
How can i do to store expressions in a notebook so that i could them directly with reevaluating all my notebook ?
Thanks you for you tips.
