That's because that one is just on its own not a power of an exponential

What about the parametric differentiation q where you had to give the second derivative in terms of y?

Yea yea you are right. The I forgot the the shape for a sec
15. what did you get for d2y/d2x in terms of t
16. So for hh(x), was h-1(x) = h(x)?
17. (Original post by FusionNetworks)
So for hh(x), was h-1(x) = h(x)?
Yeah and then 1/9 when subbed the value in?
18. (Original post by FusionNetworks)
So for hh(x), was h-1(x) = h(x)?
Yeah I did that, and for b i got 1/9
19. (Original post by Mango88)
what did you get for d2y/d2x in terms of t
If I remember correctly: -1/8cos^3(3t)
20. What did you guys do for 2 part b?
