The sequence u1,u2, ...... , un ,...is defined by
and u 1 =1, u2 = 1. Express un in terms of n and justify your answer.
By considering the expansion of
or otherwise, evaluate the n derivative of
when x = 0.
Solving the differential equation,
Does it make sense?
Find the number of ways to permute 6 “s”s and 4 “f”s in a row.
Is the answer or
If X Bin (n, p), then
If you suspect a statement is TRUE, try to prove it; if you think that it is FALSE, try to look for a counter-example to disprove the statement. Get students to think over the logical statement. Lead students to communicate in acceptable mathematical language
