LOST UPDATE problem occurs when two transactions both read old value of variable and use that value to calculate new value .
INCONSISTENT RETRIEVAL problem occurs when a retreival transaction observes value that are involved in an ongoing updating transaction.
it had to many problems
not many problems, only that you would get the problem wrong:)

Quadratic equations can be used in solving problems where the formula is given, falling object problems and problems involving geometric shapes.All types of engineering professions use the quadratic formula since it applies to ordinary differential equations.
It would have different measurements
The three most common concurrent transaction executive problems are uncommitted data, lost updates, and inconsistent retrievals. It is believed that concurrency control can help these problems.

several problems can occur when concurrent transaction execute in an uncontrolled manner.
By having concurrency control you avoid dirty writes (or inconsistent data). It is like your traffic signal - allows one set of users (drivers) to pass through at a time. In computer terms, if a user wants to update some data then the following steps are taken: (a) the data is fetched along with the timestamp (the date, time when it was last modified) (b) the data is modified by the user who then submits the data for update / storage in the system (c) the system verifies the original timestamp with the current timestamp. (i) If both are same, the new data (including the new timestamp) is updated/stored in the system. (ii) If they are different, then obviously the data had changed between the time it was fetched and now - meaning that someone else had updated in the meanwhile. The system typically informs the user that the data had been modified by a different user and asks him/her to submit the modifications once again. The system would implicitly do step (a) above allowing the user to start from step (b) onwards.
Some problems with measuring include inaccuracies due to human error, inconsistent measurement techniques, equipment calibration issues, and environmental factors that can affect measurements.
Some problems might arise if a parent is inconsistent in his/her style. The child might become confused as to what he/she needs to do. The child might not understand when the parent is being serious, or is joking. The ever changing atmosphere in the house can surely be detrimental to a child.
Incomplete locking refers to a situation in a database management system where a transaction does not acquire all the necessary locks on the resources it needs before it begins its operations. This can lead to issues such as lost updates, dirty reads, or other concurrency problems, as other transactions may modify the data while the first transaction is in progress. Incomplete locking can compromise data integrity and lead to inconsistent states within the database. To prevent this, proper locking protocols and isolation levels should be implemented.
Common problems experienced with Samsung side by side refrigerators include issues with the ice maker, temperature control, and water dispenser. These problems can lead to inconsistent cooling, leaks, and ice buildup, requiring maintenance or repairs.
Your cartridges may not be working properly because refilling ink cartridges is not recommended by the manufacturer. The consistency of these inks can be inconsistent, causing the printing problems. Purchasing the recommended cartridges should fix your problems.
Common issues that can arise with well pump pressure switch problems include inconsistent water pressure, frequent cycling of the pump, and potential damage to the pump motor.
Common problems with the Institutional Review Board (IRB) system include delays in the review process, inconsistent interpretations of regulations, lack of diversity in IRB membership, and potential conflicts of interest among board members.
Common issues that can arise with water pressure reducing valve problems include inconsistent water pressure, water hammering noises, leaks, and damage to appliances and plumbing fixtures.
