hyperspace navigator help

+ HYPERSPACE NAVIGATOR is a game about designing trajectories using parametric curves. These are curves where y is not determined by some function of x (e.g. y = f[x]), but where both x and y are determined by a third quantity t, which we might think of as time. + Parametric curves are capable of producing complex and beautiful shapes from relatively simple definitions, and I encourage you to play with the system to see what you can create! +

+ While defining your parametric curves, you have access to the following operations: +

Addition (t+2)
Subtraction (2-t)
Multiplication (2t or 2*t)
Division (t/2)
Exponents (t^2)
Modular arithmetic (t mod 2 or t % 2)
Trigonometric functions (tan, sin, cos, acos, asin, atan, atan2)
Miscellaneous extra functions (abs, exp, log, sqrt, ceil, floor, random, round)
Mathematical constants (pi, e)
