Hello i need some with trigonometric substitutions. [tex]\int\limits^a_b {x} \, dx[/tex]

Refer to interactive solution 17.45 to review a method by which this problem can be solved. the fundamental frequencies of two air columns are the same. column a is open at both ends, while column b is open at only one end. the length of column a is 0.504 m. what is the length of column b?

What is the y intercept of f(x)=(1/2)^x?
