Took me a couple of seconds, but I wouldn't have known it if I wasn't married to an engineer!

Yep (mathphobes look away now!)

tan b is defined is sin b/cos b. The inverse of that, 1/tan b = cos b/sin b.

The equation in the image is sin b/tan b, but that can also be written as sin b times 1/tan b, which is sin b times cos b/sin b.

Now the sin b on the top line cancels with the sin b on the bottom line, leaving only...

Bill!
