good morning

I’m trying to understand how I can create curves from equations

X equation= - (29 - 23 * cos(u * pi / 6 - 0.0183)) * cos(u * pi * 8)

Y equation= - (29 - 23 * cos(u * pi / 6 - 0.0183)) * sin(u * pi * 8)

Z equation= - 23 * sin(u * pi / 6 - 0.0183)

U Min -1

U Max 1

Step 1024

if you can explain to me why i have difficulty using grasshopper

Thank you for your attention

regards
