Question

Hello,

I am confused on how to approach and solve this problem.

r(t) = (8te¹ — 6)i + (sin(3t) − 2)j + (4 ln(t + 1) + 5)k.
dr
(a) Compute (0) and (0). Show your process.
dt
(b) Use your answer from part (a) to find the equation equation for the line tangent to the curve
at t = 0.
dr
(c) Explain how (0) and the tangent line are related geometrically.
dt
