## How to make a legend box?...

Maple 2022

How can I make a legend for this plot?

`plot([17.85*(2.65*t^2 + 1 + 3*t)^2/t^2, 17.85*(2.65*t^2 - 47 + 3*t)^2/t^2, 17.85*(2.65*t^2 - 97 + 3*t)^2/t^2, 17.85*(2.65*t^2 - 147 + 3*t)^2/t^2, 17.85*(2.65*t^2 - 197 + 3*t)^2/t^2], t = 0 .. 25, labels = ['t', 'x'], labelfont = [Times, 12])`

I got the following figure.

Now I want to put a legend box in this plot for each color line. How can I do it?

## How to evaluate an expression for multip...

Maple 2022

Suppose I have an expression like the following:

```h(t, x) :=  (m*t^2 + 6*t - 2*x)^2/(36*g*t^2)
```

I want to calculate multiple values of t in a single expression. Say, for t:= 1,5,10,15,20. I want to evaluate h(t,x) in vector form. so that I can extract for each t. How to write it?

## How to multiply two row vector componen...

Maple 2024

Suppose I have, a row vector  R = [R1 , R2  , R] and a column vector C =  [C1 , C2  , C]. I need a multiplication like as follows

RC = [ R1 [C], R2[C], R3 [C]  ], so that RC will be a 3/3 matrix.
