Page 113 - The derivative of the sum of two functions is the sum of their derivatives. Proof. Let the two functions be u and ». and let their values, arising from an infinitesimal change i in the value of their variable, be «' and v'; the increase of their sum will be («, + »') -(« + ») or «' U -\- V > V, and therefore the derivative of the sum is u' — uv, — v -T I ' i which is obviously the sum of their derivatives.

Page 230 - Rule. 324. An equation of any degree whatever cannot have a greater number of positive roots than there are variations in the signs of Us terms, nor a greater number of negative roots than there are permanences of these signs.
