Pa X se unosi zato, sto je on promenljiva, koja ide od -2, -1.9, -1.8...... -0.2, 0.1,0.0.
Za svaku tu vrednost X-a treba da izracunas, kolijo je f, i da ga smestis u niz.
Ne mogu da skapiram sta ti nije jasno. Kako to programerski da izvedes, ili si slab u matematici (verovatno ovo drugo).
Evo mala ideja, pa ti razradi.
Code:
var f: array[0..20] of real;
i:integer;
begin
for i := 0 to 20 do
f[i]:= (i*0.1)*(i*0.1)-1;
end.
Eh, sad si dao ceo zadatak.
Neka je:
Edit1=x
Label1=rezultat
Code:
Button1.click:
label1.caption=sqr(strtoint(edit1.text))-1
Button2.click:
for i = 0 to 20
f[i]=sqr(i*0.1)-1
Button3.click:
napravi sam
Button4.click:
assign(out)
reset(out);
for i = 0 to 20
write(out,f[i])
close(out)
