Step-by-step Solution
It seems like there are some formatting issues in your integral expression. However, I will try to interpret it and provide a solution based on what I can understand.
If you meant to evaluate the integral of the form:
\[
\int_{1}^{64} \frac{\cos^2(x)}{\sin(x) \cos(x)} \, dx
\]
we can simplify the integrand. The expression \(\frac{\cos^2(x)}{\sin(x) \cos(x)}\) can be rewritten as:
\[
\frac{\cos^2(x)}{\sin(x) \cos(x)} = \frac{\cos(x)}{\sin(x)} = \cot(x)
\]
Thus, the integral becomes:
\[
\int_{1}^{64} \cot(x) \, dx
\]
The integral of \(\cot(x)\) is:
\[
\int \cot(x) \, dx = \ln|\sin(x)| + C
\]
Now, we can evaluate the definite integral:
\[
\int_{1}^{64} \cot(x) \, dx = \left[ \ln|\sin(x)| \right]_{1}^{64}
\]
Calculating this gives:
\[
\ln|\sin(64)| - \ln|\sin(1)|
\]
This can be simplified to:
\[
\ln\left(\frac{|\sin(64)|}{|\sin(1)|}\right)
\]
To find the numerical values of \(\sin(64)\) and \(\sin(1)\), you can use a calculator or software that computes trigonometric functions.
If you meant a different integral or if there are additional details, please clarify, and I would be happy to assist further!
Quick Answer
Evaluate the integral \(\int_{1}^{64} \cot(x) \, dx\) by calculating \(\ln\left(\frac{|\sin(64)|}{|\sin(1)|}\right)\).
