vector-valued function: r(t) = cos (ti) + 2 sin (tj) if r(pi/6 - delta*t) - r(pi/6

[llmd5dk4]

vector-valued function:

r(t) = cos (ti) + 2 sin (tj)

if

r(pi/6 - delta*t) - r(pi/6)

 

[stapel]

vector-valued function:

r(t) = cos (ti) + 2 sin (tj)

if

r(pi/6 - delta*t) - r(pi/6)

I'm sorry, but I don't understand what this means...?
