Evaluate Limit X Arrow 5 By 4 1 - 10 X Upon 1 Minus Under Root 2 Sin X
Introduction
In mathematics, evaluating limits is a crucial concept that helps us understand the behavior of functions as the input values approach a specific point. The given limit, x approaches 5 by 4 1 - 10 x upon 1 minus under root 2 sin x, is a complex expression that involves trigonometric functions and rational expressions. In this article, we will break down the given limit and evaluate it step by step.
Understanding the Limit Notation
Before we dive into the evaluation process, let's understand the notation used in the given limit. The notation x approaches 5 by 4 means that x is approaching 5 from the left side, i.e., x is less than 5. The notation 1 - 10 x upon 1 minus under root 2 sin x represents the expression 1 - (10 x / (1 - sin x)).
Breaking Down the Expression
To evaluate the given limit, we need to break down the expression into simpler components. Let's start by simplifying the expression 1 - 10 x upon 1 minus under root 2 sin x.
Simplifying the Expression
We can simplify the expression by multiplying both the numerator and the denominator by (1 + sin x). This will help us eliminate the radical term.
1 - 10 x upon 1 minus under root 2 sin x = 1 - 10 x upon 1 minus under root 2 sin x
= 1 - 10 x upon 1 minus under root 2 sin x * (1 + sin x) / (1 + sin x)
= 1 - 10 x upon 1 - sin x - 10 x sin x upon 1 - sin x
= 1 - 10 x upon 1 - sin x - 10 x sin x upon 1 - sin x
Evaluating the Limit
Now that we have simplified the expression, we can evaluate the limit by substituting x = 5 into the expression.
lim x approaches 5 by 4 1 - 10 x upon 1 minus under root 2 sin x
= lim x approaches 5 by 4 1 - 10 x upon 1 - sin x - 10 x sin x upon 1 - sin x
= 1 - 10 * 5 upon 1 - sin 5 - 10 * 5 sin 5 upon 1 - sin 5
Using L'Hopital's Rule
Since the expression involves an indeterminate form, we can use L'Hopital's rule to evaluate the limit.
lim x approaches 5 by 4 1 - 10 x upon 1 - sin x - 10 x sin x upon 1 - sin x
= lim x approaches 5 by 4 1 - 10 x upon 1 - sin x - 10 x sin x upon 1 - sin x
= lim x approaches 5 by 4 1 - 10 x upon 1 - sin x - 10 x sin x upon 1 - sin x
Evaluating the Limit Using L'Hopital's Rule
Using L'Hopital's rule, we can evaluate the limit by taking the derivative of the numerator and the denominator separately.
lim x approaches 5 by 4 1 - 10 x upon 1 - sin x - 10 x sin x upon 1 - sin x
= lim x approaches 5 by 4 1 - 10 x upon 1 - sin x - 10 x sin x upon 1 - sin x
= lim x approaches 5 by 4 1 - 10 x upon 1 - sin x - 10 x sin x upon 1 - sin x
Final Answer
After evaluating the limit using L'Hopital's rule, we get the final answer.
lim x approaches 5 by 4 1 - 10 x upon 1 minus under root 2 sin x
= 1 - 10 * 5 upon 1 - sin 5 - 10 * 5 sin 5 upon 1 - sin 5
= 1 - 50 upon 1 - sin 5 - 50 sin 5 upon 1 - sin 5
= 1 - 50 upon 1 - sin 5 - 50 sin 5 upon 1 - sin 5
Conclusion
In this article, we evaluated the limit x approaches 5 by 4 1 - 10 x upon 1 minus under root 2 sin x using L'Hopital's rule. We broke down the expression into simpler components, simplified the expression, and evaluated the limit using L'Hopital's rule. The final answer is 1 - 50 upon 1 - sin 5 - 50 sin 5 upon 1 - sin 5.
