Hi: I was wondering how to solve differential equations symbolicaly in Mathcad. Is there anyone that can help? I know how to solve for example y"-y'-y=0 manually but I like to hand my homework in Mathcad but I have to type it in Word because I have not figure out how Mathcad can do this.
Mathcad has no direct facilities for symbolic solutions of differential equations, and limited facilities for assisting you.
For your particular case, and other similar simple cases, you can use Laplace transforms. You take the Laplace transform of the differential equation, manually substitute the initial values for the expressions representing them, solve for the Laplace transform of y(x), and then take the inverse Laplace transform.
