3. Give a combinatorial proof of the following identity. ("t?) = () + (-1) where n and k are positive integers with n > k. 5. Give a combinatorial proof of the following identity (known as the Hockey Stick Identity). (%) + (**") + (**?) + ... + ( )= (#1) where n and k are positive integers with n > k.
8.14. Give a combinatorial proof of the following binomial identity: 3 0) (+) = ---() = 2n-m k= m (Hint: Think of the number of ways of picking two disjoint subsets from a set of cardinality n so that one subset is of cardinality m and the other subset is arbitrary.)
Give asymptotic tight bound for T(n) = 71(n/2) + n2. Assume that T(n) is constant for n < 2. A. n2 B. n to the power of log subscript 2 7 end exponent C. nalogn D. n to the power of log subscript 2 7 end exponent log n
(1) Using the identity: n n! (2) want k k!(n - k)! for n > 1, prove the following identity: ()-20) + n2
Therom 1.8.2 n choose k = (n choose n-k) n choose k = (n-1 choose K) + (n-1 choose K-1) 2n = summation of (n choose i ) please use the induction method (a) (10 pts) Show that the following equality holds: n +1 + 2 Hint: If you proceed by induction, you might want to use Theorem 1.8.2. If you search for a combinatorial proof, consider the set X - (i,j, k): 0 S i,j< k< n) (b) (10...

Use induction and Pascal's identity to prove that (7) = 2" where n > 0.
1. Use an identity to find the exact value of cos(?) given that cos(O) = { with 270° << 360°
Use induction to prove that 0–0 4j3 = n4 + 2n3 + n2 where n > 0.
Using the identity sin? 0 + cos² 0 = 1, find the value of tan 6, to the nearest hundredth, if sin 0 = -0.62 and 3 < 0 < 27.
