RE: deTaylor
thank you!
please help to control with an differential equation still not solvable in Prime (but now ok in XCas): y'=(x+y)^2 Is it correct to input deTaylor((x+y)^2, [x,y], [0,0], 7) ? I get (17/315)x^7+(2/15)x^5+(β )x^3 The general solution of equation (XCas) is TAN(xc)x With Taylor I've taylor(TAN(x)x), x, 6) = (β )x^3+(2/15)x^5+x^7+o(x) It should be ok, isn't it?
