definition of limit to prove that lim ,-e3. 3, (a) Use the - (b) Suppose lim g(z) 0 and if(x)| |g(z)| for all z E R. Use the ε-δ definition of limit to prove that lim f(x)=0 definition of limit to prove that lim ,-e3. 3, (a) Use the - (b) Suppose lim g(z) 0 and if(x)| |g(z)| for all z E R. Use the ε-δ definition of limit to prove that lim f(x)=0
3) Complete the following to prove lim (4x – 3)= 5 using the epsilon-delta definition of a limit. x2 Part 1: Analysis (i.e. "guess” a 8) For every we need to if then (Complete these steps as you want in order to find delta.) This suggests that we should choose Part 2: Proof: (show that this choice of satisfies the definition of a limit). Given choose If then Thus, if , then Therefore, by Q.E.D.
Prove the statement using the ε, δ definition of a limit. Prove the statement using the ε, definition of a limit. lim x → 1 6 + 4x 5 = 2 Given a > 0, we need ---Select--- such that if 0 < 1x – 1< 8, then 6 + 4x 5 2. ---Select--- But 6 + 4x 5 21 < E 4x - 4 5 <E |x – 1< E = [X – 1] < ---Select--- So if we...
**please note the limit definition has an "a"** 1. (5 points) Use the limit definition to find the derivative of f(x) = 3x2 – 2+1 at x = 4. Show all steps and setup f(a+h)-f(a) lim h h0
Use this definition of a right-hand limit to prove the following limit. EXAMPLE 3 x0 SOLUTION and L such that 1. Guessing a value for 6. Let & be a given positive number. Here a = so we want to find a number 0 x6 if then that is if 0 <x<6 then <E or, raising both sides of the inequality to the eleventh power, we get 0 <x if then x < This suggests we should choose 8= 2....
