How do you find maximum velocity?
Using Calculus If acceleration is positive to the left and negative to the right, the point is a maximum velocity. In the example, a=3cos(t) is positive just before t=π /2 and negative just after, so it is a maximum; however, 3π/2 is a minimum because a=3cos(t) is negative just before 3π/2 and positive just after.
How do you calculate the height of a tree?
The height of a binary tree is found using the recursive Depth-First Search (DFS) algorithm, as shown below:
- Base case: If there is no node, return 0.
- Else: If there are 1 or 2 children, return the maximum of the height of the left and right sub-trees, plus 1 to account for the current node.
What is width and height?
