Taylor polynomial of e^{kx}
Guided practice — solve each problem, check, then generate a fresh one.
Formula to apply
e^{kx} ≈ 1 + kx + (kx)²/2 + (kx)³/6
Problem
Compute the degree-3 Taylor polynomial of e^{2x} at x = 0.
Working
- 1T₃(x) = 1 + 2x + (2x)²/2 + (2x)³/6.
- 2At x = 0: kx = 0.
- 3T₃ = 1 + 0 + 0 + 0 = 1.
