Since none of these ... Mar 29, 2022 ... We evaluate the limit of 1-cosx / x as x goes to 0. This is a fundamental limit you're expected to know, so let's see where it comes from! The period of the cos(x) cos ( x ) function is 2π 2 π so values will repeat every 2π 2 π radians in both directions. At x> π, sin(θ) goes from 0 to -1 at 3π/2, then back to 0 at 2π. At this point the sin values repeat. The period of the sine function is 2π. To graph a more ...
