I get (a) part but for the last part to find the vertical distances can someone explain what is done here. This is the solution

let h be the vertical distance

h = y + xtan30

h= vot tan30 - 1/2gt^2

then they differentiate to find maximum (i get that part). I just dont understand how they came up with those equations for the h distance...

can anyone explain?
