Hi Alesna, could you try my codes below? Good luck.
clc; clear; close all;
syms y(t) k t
Dy=diff(y);
k=sqrt(2);
ode=diff(y,t,2)==k*sin(k*t);
conds = [y(0)==6, Dy(0)==0];
ySol(t)=dsolve(ode,conds)

Try these codes below. Good luck.
clc; clear; close all;
syms y(x)
Dy = diff(y);
ode = diff(y,x,2) == -5*diff(y,x)-4*y;
cond1 = y(0) == 1;
cond2 = Dy(0) == 0;
conds = [cond1 cond2];
ySol(x) = dsolve(ode,conds);
ySol = simplify(ySol);
ySol(1)

You created y as a symbolic function, syms y(t)
You try to assign to ySol(y) . But y is a function, and you cannot index by a function.
You could assign to ySol(t)
