In summary, a one-sided limit in calculus is the value that a function approaches as the input approaches a specific value from either the left or the right side. The one-sided limit of sin(x)/x at x=0 is equal to 1, which is calculated using the limit definition in calculus. This limit is important because it helps us understand the behavior of the function near the point x=0. The one-sided limit is equal to the two-sided limit in this case, as the function is continuous at x=0.

find the one sided limit at the point x=0 for functions

f(x)={ sinx/x, x greater than 0 ; x+1, x less or equal than 0

Hi spartas,

The first limit can be solved using "the squeeze theorem". Here is a hint.
$$ \cos(x) < \frac{\sin(x)}{x} < 1 $$
What happens to the left and right sides for $\displaystyle \lim_{x \rightarrow 0}$?
 

FAQ: One-Sided Limit of Sin(x)/x at x=0

What is a one-sided limit?

A one-sided limit is a concept in calculus that refers to the value that a function approaches as the input approaches a specific value from either the left or the right side. In other words, it is the value that the function gets closer and closer to, but may not actually reach, as the input approaches a certain point.

What is the one-sided limit of sin(x)/x at x=0?

The one-sided limit of sin(x)/x at x=0 is equal to 1. This means that as the input (x) approaches 0 from either the left or the right side, the function sin(x)/x gets closer and closer to the value of 1.

How is the one-sided limit of sin(x)/x at x=0 calculated?

The one-sided limit of sin(x)/x at x=0 can be calculated using the limit definition in calculus, which involves plugging in values that are very close to 0 (but not equal to 0) into the function and seeing what value the function approaches. In this case, as the values get closer and closer to 0, the function approaches the value of 1, indicating that the one-sided limit is equal to 1.

Why is the one-sided limit of sin(x)/x at x=0 important?

The one-sided limit of sin(x)/x at x=0 is important because it helps us understand the behavior of the function sin(x)/x near the point x=0. It tells us that as the input gets closer and closer to 0, the function gets closer and closer to the value of 1, which can be useful in various applications of calculus.

Can the one-sided limit of sin(x)/x at x=0 be different from the two-sided limit?

No, the one-sided limit of sin(x)/x at x=0 is equal to the two-sided limit. This is because the function sin(x)/x is continuous at x=0, meaning that the limit from the left side and the limit from the right side are equal to each other. Therefore, the one-sided limit and the two-sided limit are both equal to 1.
