Explanation of Solution
Circumstances for early releasing a lock
- The strategy for early releasing the lock is to go down the tree from the root.
- Except the current node, the locks that are held on all nodes are released and then an X-lock on the child node is requested.
- After getting the X-lock, the lock on the current node is released and then descend to the child node.
- If the child node is full, then retain all the locks that are held and then an X-lock for the child node is requested.
- After getting the lock, then descend to that node.
- The insertion procedure is started after reaching the leaf node...

In other words, you will program the sine or cosine function yourself, without using any existing solution. You can enter the angles in degrees or radians. The program must work for any input, e.g. -4500° or +8649°. The function will have two arguments: float sinus(float radians, float epsilon); For your own implementation, use one of the following relations (you only need to program either sine or cosine, you don't need both): Tip 1: Of course, you cannot calculate the sum of an infinite series indefinitely. You can see (if not, look in the program) that the terms keep getting smaller, so there will definitely be a situation where adding another term will not change the result in any way (see problem 1.3 – machine epsilon). However, you can end the calculation even earlier – when the result changes by less than epsilon (a pre-specified, sufficiently small number, e.g.…arrow_forward
