Understanding the Relationship Between Logarithms and Inverse Hyperbolic Functions

When dealing with logarithmic and inverse hyperbolic functions, it's essential to understand the relationships between them. In this article, we will explore the concept of inverse hyperbolic functions and their connection to logarithms.

What is the Inverse Hyperbolic Function?

The inverse hyperbolic function, denoted as $\operatorname{In}(x)$ , is a mathematical function that is the inverse of the hyperbolic sine function, $\sinh(x)$ . The hyperbolic sine function is defined as $\sinh(x) = \frac{e^x - e^{-x}}{2}$ , and the inverse hyperbolic function is defined as $\operatorname{In}(x) = \ln\left(\sqrt{\frac{x+1}{x-1}}\right)$ .

The Relationship Between Inverse Hyperbolic Functions and Logarithms

The inverse hyperbolic function, $\operatorname{In}(x)$ , is closely related to the natural logarithm function, $\ln(x)$ . In fact, the inverse hyperbolic function can be expressed in terms of the natural logarithm function. Specifically, $\operatorname{In}(x) = \ln\left(\sqrt{\frac{x+1}{x-1}}\right)$ .

Calculating $\operatorname{In}(1.7)$

When you calculate $\operatorname{In}(1.7)$ , you are essentially finding the value of the expression $\ln\left(\sqrt{\frac{1.7+1}{1.7-1}}\right)$ . This expression can be simplified as follows:

$\ln\left(\sqrt{\frac{2.7}{0.7}}\right) = \ln\left(\sqrt{3.8571}\right) = \ln(1.9635)$

Finding the Value of the Expression

Now that we have simplified the expression, we can see that it is equivalent to finding the value of $\ln(1.9635)$ . This is a logarithmic expression, and it can be evaluated using the properties of logarithms.

Evaluating the Logarithmic Expression

To evaluate the logarithmic expression, we can use the fact that $\ln(x) = \log_e(x)$ . Therefore, we can rewrite the expression as $\log_e(1.9635)$ .

Conclusion

In conclusion, when you calculate $\operatorname{In}(1.7)$ , you are finding the value of the expression $\log_e(1.7)$ . This is a fundamental property of inverse hyperbolic functions and logarithms, and it highlights the close relationship between these two mathematical functions.

Answer to the Question

Based on the above discussion, the correct answer to the question is:

A. $\log _e(1.7)$

This is because $\operatorname{In}(1.7)$ is equivalent to finding the value of $\log_e(1.7)$ .

Additional Information

It's worth noting that the other options are not correct. Option B, $\log _{10}(1.7)$ , is a logarithmic expression with base 10, whereas $\operatorname{In}(1.7)$ is a logarithmic expression with base $e$ . Option C, $\log _{1.7}(10)$ , is a logarithmic expression with base 1.7, whereas $\operatorname{In}(1.7)$ is a logarithmic expression with base $e$ . Option D, $\log _{1.7}(e)$ , is a logarithmic expression with base 1.7 and argument $e$ , whereas $\operatorname{In}(1.7)$ is a logarithmic expression with base $e$ and argument 1.7.

Final Thoughts

In conclusion, the inverse hyperbolic function, $\operatorname{In}(x)$ , is closely related to the natural logarithm function, $\ln(x)$ . When you calculate $\operatorname{In}(1.7)$ , you are finding the value of the expression $\log_e(1.7)$ . This highlights the importance of understanding the relationships between different mathematical functions and their properties.
