960 cups of alcohol (or 60 gallons)
360 gallons of water
240 cups of ammonia (or 15 gallons)
Take total and divide by 8 , so 1280 divide by 8 is 160. now multiply each amount by 160. *(remember there are 16 cups in a gallon . So you dived total amount of cups by 16 to convert it to gallons)
Answer:
the smallest even number is32
The problem ask to fourier series of the trigonometric function base on the data you have been given in the problem, so the answer would be cos(pi/2n) = {(-1)^n/2 - if n is even, 0 - if n is odd} and sin(pi/2n) = {0- if n is even, (-1)^(n-1)/2 if n is odd}. I hope you are satisfied with my answer
