I want to solve two simultaneous second-degree differential equations. Which solver can I use for it? If I use dsolve, in which form should I input equations?

The dsolve function is part of the Symbolic Math Toolbox, so you would enter your equations as symbolic functions and then use dsolve to solve them. See the documentation on dsolve for details.

You can also use the Symbolic Math Toolbox to set up (but not solve) nonlinear differential equations to use in ode45, ode15s, and others. You will find the odeToVectorField and matlabFunction functions invaluable.
