Use the shell method to find the volume of the solid of revolution obtained by rotating the region bounded by y = 1 and y = tan x about the x-axis from x = 0 to x = π / 4.

you can't solve x because it is 2 linear equation and you only have one equation

answer: 0

step-by-step explanation: the positive, like 5, + its opposite, like -5 would be 0

5+(-5)=0, or 5-5=0

- (2, -7)

- lines r and s and lines t and u must be parallel
