Question
Find the limit (if it exists). (If an answer does not exist, enter DNE.)lim Δt→0 (t + Δt)2 − 5(t + Δt) + 2 − (t2 − 5t + 2)Δt
Solution
First, let's simplify the expression inside the limit:
(t + Δt)² - 5(t + Δt) + 2 - (t² - 5t + 2) can be expanded and simplified to:
t² + 2tΔt + Δt² - 5t - 5Δt + 2 - t² + 5t - 2
This simplifies to:
2tΔt + Δt² - 5Δt
We can factor out Δt from each term:
Δt(2t + Δt - 5)
Now, we can apply the limit:
lim Δt→0 Δt(2t + Δt - 5)
Since Δt is approaching 0, the term Δt in the expression will become 0, and we are left with:
0 * (2t - 5) = 0
So, the limit of the given expression as Δt approaches 0 is 0.
