RE: New user frustration
The manual may not be up to date and contain some typos.
What I found out for your examples, what you could try. Go to CAS mode first, then enter: diff(x^4*y^4,{x,y}{3,2}) gives the desired answer for the differentiation. For solving the equation, also in CAS mode, enter the following: zeros(c^2+d^2=1,c) This gives the two symbolic solutions for variable c in terms of d. If you don't get the correct results, make sure the variables (x,y,c,d) have not been assigned any values in CAS. You can check this by pushing the Vars button, then Cas->All and look into the list for these variables (should not be present there!). |
