L₁(1)→Q

L₁(2)→W

L₁(3)→R

L₁(4)→Z

L₂(1)→U

L₂(2)→O

L₂(3)→P

L₂(4)→S

"–tan(Q)X+U/cos(Q)"→Y₁

"–tan(W)X+O/cos(W)"→Y₂

"–tan(R)X+P/cos(R)"→Y₃

"–tan(Z)X+S/cos(Z)"→Y₄

HI guys, is it possible to AVOID the first L₁(1)→Q, L₁(2)→W …. part? and simply having something like this:

"–tan(L₁(1))X+U/cos(L₂(1))"→Y₁ ???

"–tan(L₁(2))X+O/cos(L₂(2))"→Y₂

…

Basicaly most L1, L2 variable just get imported into the equasion? i need so max. 7 tangents because if i define the variables too much there may be overlapping.

Because I have L1 and L2 variables and i want that they be PLOTED automaticaly with out predifining them.

THank yoU!
