Find the exact length of the curve:
x=5+15t^2
y=6+2t^3
0, greater than or = to, t, greater than or = to, 4
The other problem is:
Find equations of tangents to x=3t^2+8, y=2t^3+8, that passes through (11,0).
I had NO idea how to do those. I did a couple steps of each and got to something that I'm unsure of. Any help would be greatly appreciated!
