xx(t)= 6(1-cos(t/2)) yy(t)= 20t(1-sin(t))(cos(t/2))^2 0

Question

xx(t)= 6(1-cos(t/2)) yy(t)= 20t(1-sin(t))(cos(t/2))^2  0<t<pi measure the volume inside these two parametric equation

Sorry I don't know this
@TuringTest might be able to help

turingtest · Answer

I'm not familiar with the notation xx(t) and yy(t)

turingtest · Answer

why is there an extra variable?

anonymous · Answer

what do you mean by extra variable?

anonymous · Answer

xx(t) and yy(t) is parametric function

turingtest · Answer

I just write x(t) or y(t)
never seen the double x or y before

turingtest · Answer

this is strange, you have a parametric function with two dependent variables, x and y
that's a two-dimensional figure, how can it have a volume?

turingtest · Answer

how is the question literally?
does it maybe read more like 
find the region bound by....

anonymous · Answer

the xx(t) and yy(t) just two functions...it could be seen as x(t) and y(t) it doesnt' matter

anonymous · Answer

just find the region bound by these two parametric equations volume
