The question involved solving the "T" on a plate sized from (0,0) to (1,2). Any ways, I will spare you of the details and get to the line in the solution I was confused with:(adsbygoogle = window.adsbygoogle || []).push({});

Bottom: T(x,0) = 1-x = B_{n}(sinh 2n∏) (sin n∏x) = b_{n}(sin n∏x)

The next line confused me: b_{n}= 2_{0}∫^{1}(1-x) sin n∏x dx

How did they arrive at that equation to solve for b_{n}? thanks

(forgot to read the stickies, move this post if you wish, thanks)
