Input "T START:",A
Input "T STOP:", B
Input "T STEP:", S
int((B-A)/S) → N
A → T: {X1T} → L1 : {Y1T} → L2
{X2T} → L3: {Y2T} → L4
For(I,2,N)
A + S*(I-1) → T
augment(L1, {X1T}) → L1
augment(L2, {Y1T}) → L2
augment(L3, {X2T}) → L3
augment(L4, {Y2T}) → L4
Plot1(Scatter, L1, L2, □, BLUE)
Plot2(Scatter, L3, L4, □, GREEN)
DispGraph
Wait 1
End
Example
X1T = 2 SIN T
Y1T = 3 SIN T
X2T = SIN (T^2/4)
Y2T = 1/2 * COS(T^2/8)
T START: 0
T STOP: 4 * π
T STEP: π / 24
