what is mean by "t" while defining the curve by equation in creo parametric

creo parametric
curve definition equation

x = 50 * t

y = 10 * sin (t * 360)

Just to clarify, the curve is created over the domain of values from t=0 to t=1.

t is a parameter to define your curve and should be given as a range.
The formulas x=... and y=... must be calculated for each t and are called the parameter representation of your curve

Set the range of t to approbriate start and end and calculate for each t the values of x and y. The values of x and y are pairs of coordinates to define your curve

example t=0..5 x=t y=3*t would give a linear connection between the points (0/0), (1,3), (2,6), (3,9), (4,12) and (5,15)
