Use a recursion tree to determine a good asymptotic upper bound on the recurrence T(n) = 3T(\lfloor n / 2 \rfloor) + nT(n)=3T(⌊n/2⌋)+n. Use the substitution method to verify your answer.

Hello! i hope this
since the cosine is the ratio of the adjacent side to the hypotenuse, you can see that cos 60° = ½. answer. according to the property of cofunctions (topic 3), sin 30° is equal to cos 60°. sin 30° = ½.
