Homework Statement Lim x-> 0 Sin(x) + Cos(x) + e^-x - 2 / Sin(x) - x The Attempt at a Solution Sin(x) + Cos(x) + e^-x - 2 = 0 and Sin(x) - x = 0 This is indeterminate form? I used L'Hopitals rule 3 times to get -Cos(x) + Sin(x) - e^-x / -Cos(x) The top equals -2 and...

Homework Statement V = the set of all symetrical nXn matrices, A=(ajk) such that ajk=akj for all j,k=1,...,n Determine the base and dimensions for V The Attempt at a Solution I set my matrix up as [a11 a12] [a21 a22] So a21 and a12 are equal to each other? I assume the...
