What is the value of Sinx x as x approaches to zero?

1
Showing that the limit of sin(x)/x as x approaches 0 is equal to 1.

What is the limit of Cos x x as x approaches 0?

Showing that the limit of (1-cos(x))/x as x approaches 0 is equal to 0.

What is the limit of Sinx x as x approaches infinity?

zero
We know that the limit of both -1/x and 1/x as x approaches either positive or negative infinity is zero, therefore the limit of sin(x)/x as x approaches either positive or negative infinity is zero.

Why does sin xx equal 1?

Definition: “Hypotenuse” is the longest side of a right triangle, opposite the right angle. Per definition, the radius of the unit circle is equal to 1. Therefore, the hypotenuse, AC, of the smaller triangle must be 1. If we wanted to find the sin value of x, by definition, it would have to be sin(x) = BC/1.

What is the limit as x approaches 0 of X X?

Consider the right sided limit. Make a table to show the behavior of the function |x|x as x approaches 0 from the right. As the x values approach 0 , the function values approach 1 . Thus, the limit of |x|x as x approaches 0 from the right is 1 .

For what value is Sinx X?

sinxx is an entire function. That is it is holomorphic at all finite points in the complex plane (taking its value at x=0 to be 1 ).

What is the limit of sin(x)/x as x approaches 0?

Showing that the limit of sin (x)/x as x approaches 0 is equal to 1. If you find this fact confusing, you’ve reached the right place! This is the currently selected item.

What is the value of sin x/x?

sin x / x = sin (-pi/4) / (-pi/4) = (-sqrt (2) / 2) / (-pi/4) = sqrt (2)/2 / (pi/4) Therefore, for any value of x in the first and fourth quadrant, sin x/x will be positive. Since taking the absolute value becomes redundant at this point, Sal removes them at 6:44

What is the range of sin (1/x)?

The range of sin x is [-1,1], so the range of sin (1/x) is also [-1,1]. Because the limit of x as x→0 = 0, multiplying this by sin (1/x) will give us 0 (because range of sin (1/x) is bounded).

How do you determine the limit of x x?

Evaluate the limit of x x by plugging in 0 0 for x x. The expression contains a division by 0 0 The expression is undefined. Since 0 0 0 0 is of indeterminate form, apply L’Hospital’s Rule.
