RE: Displaying ∂u/∂t but only get ∂u() and displaying 2nd order ode
It is inexplicable but I managed to be able to express the numerator and demominator of a partial derivative.
Nevertheless, if there is a method to get a numerator and denominator such as ∂u/∂x instead of ∂() I would be happy. I managed to get a double derivative such as ∂²u/∂x² Example Suppose we have a 2nd order ode of y"+3*y'=0 A solution is: y = C1 + C2*e^(3x) In the prime: desolve(∂(∂u/∂x)∂x+3*∂u/∂x=0,x,y) G_0*e^(3x) + G_1 To achieve ∂(∂u/∂x)∂x 1. Press the top row, third button from the left select ∂ /∂. 2. On the numerator of ∂ /∂ place ∂u/∂x. On the denominator of ∂ /∂ place an x to finally make it ∂(∂u/∂x)∂x Thank you Anthony, Sydney
