How to type equations

Derivatives in time: y'', \dot{x}, \frac{dy}{dt}
Partial derivatives: u_t, u_xx, u_tt, \frac{\partial u}{\partial t}, \nabla^2 u
Systems: One equation per row, e.g. x'=y and y'=-x
Parameters: Any other letter (k, \omega, k_1) becomes a slider
Functions: sin cos exp ln sqrt abs, comparisons like |x|<0.3 for step shapes
