Web1 aug. 2024 · Solution 2 Hint: To do it with induction, you have for n = 1, n 4 − 4 n 2 = − 3, which is divisible by 3 as you say. So assume k 4 − 4 k 2 = 3 p for some p. You want to prove ( k + 1) 4 − 4 ( k + 1) 2 = 3 q for some q. So expand it, insert the 3 p you know about, and you should find the rest is divisible by 3. Web12 aug. 2015 · $\begingroup$ There are so many things wrong with part (a) I truly wonder how someone could assign that as an induction problem: 1) induction is not needed, 2) strong induction is certainly not needed, etc etc. OP has good answers here though so hopefully it will all gel fairly soon. $\endgroup$ –

WebIn calculus, induction is a method of proving that a statement is true for all values of a variable within a certain range. This is done by showing that the statement is true for the first term in the range, and then using the principle of mathematical induction to show that it is also true for all subsequent terms. lampu abs menyalaWeb8 mrt. 2015 · I think I understand how induction works, but I wasn't able to justify all the steps necessary to prove this proposition: $(1+x)^n≥1+nx, ∀x>-1, ∀n∈N$ One thing that confuses me is that I don't know whether I should use induction with both x and n. I didn't pay attention to the x and I still couldn't justify all the steps.
