You have to use L'Hospital Rule. So you take the derivative of the top then you take the derivative of the bottom.
1/2 × (lim x→0 (sec²x/1))
Substitute in the x-value
1/2 × (lim x→0 (sec²(0)/1))
(lim x→0 (sec²(0)/1) = 1
1/2 × 1
1/2
        
             
        
        
        
The three principles that describe how the economy as a whole works are: (1) a country's standard of living depends on its ability to produce goods and services; (2) prices rise when the government prints too much money; and (3) society faces a short-run tradeoff between inflation and unemployment.
        
             
        
        
        
The Cold War was the war between United States and Soviet Union following the WWII. After the defeat of the axis powers and the fall of Hilter, the Soviet Union possessed the world's largest enemy. The US possessed the most powerful weapon in the atomic bomb, which had just been dropped on Hiroshima and Nagasaki to defeat Japan. Both nations had allied with one another in the war to defeat their common enemy but this was merely a front to mask the contempt both had for one another. The cold war was the term used to describe the antagonism between democratic America and communist Soviet Union (Russia). While there was never any armed notion of conflict between both nation, the cold war was the battle of ideologies and was waged in nations all over the world between proxy nation. The US goal was to spread democragy throughout the world and Soviet Union's goal was to spread communism.  
        
                    
             
        
        
        
The answer is: Motor Neurons
Explanation:
This occurs when the motor neurons deliver nerve impulses from the spinal cord to the part of the body where a response to the stimulus is needed. In the above example, the response is the muscle contraction to quickly pull the hand away from the hot pot pan.
This is simple explanation of the question.
