(cos 0pi/6, sin 0pi/6, 0pi/6) on the curve x = cost, y = sint, z = t

x(t) = ?

y(t)=?

z(t)=?

now from my understanding, i have to find the derivatives of x, y, and z right? and i did this... now alll i should do is plug in the x, y, z pts? and get the answers? i dont know if the 0pi/6 is correct cuz it was printed in w/ the problem... it could be pi/6 only and not 0pi/6.... could someone help maybe i did some kind of calculation error.... if possible explain thanks
