Euler method and RK

Hi i need to solve this equation P(t)= 24sin(35t), where intital values and final values are v_0=0m/s; S_0= 0.5; t_0=0s; t_1=1s; m=0.5; k=75; now i need to create a file where all inital values, another were precalcualtion are done and another that file that solve the equation by euler method and RK method. so far i know euler method and RK. then i need to loop them into a function that allows the user to choose the method of diffiretion. Please, i need some help getting this started. Many thanks in advance.

%EULERS METHOD
for i=1:n

y(i+1)=y(i)+0.25*f1(x(i),y(i));
x(i+1)=x(i)+0.25;
%RK 4TH ORDER
for j=1:n
  
k1=f3(x(j),y2(j));
k2=f3(x(j)+0.125,y2(j)+k1*0.125);
k3=f3(x(j)+0.125,y2(j)+k2*0.125);
k4=f3(x(j)+0.125,y2(j)+k3*0.125);
y2(j+1)=y2(j)+(0.25/6)*(k1+2*(k2+k3)+k4);
x(j+1)=x(j)+h;
end
