The lecture was excellent, and the teaching efforts (pedagogy) are highly appreciated.

If the summation starts from n=1, then, the series converges to the sum S=a*r/(1-r); in case if the summation starts from n=0, then, the series will converge to the sum S=a/(1-r). In any case, we have a quantity "a" but not "a1", and where a=1. The confusion at the end came because of writing "a1", but this is not to be considered as a mistake.

Regarding degrees or radians: Since the professor spelled out the word degrees, we can use 400 degrees to evaluate numerical value. In case if nothing is specified about 400, then radian must be used for finding numerical value.

Strictly speaking, here, 400 radians : |sin 400| = |sin(37, 9° appr)| < 1; no?
