Jul 31, 2019 · 1) In the unit circle the x represent the cosine of the function and the y represent the sine of the trigonometric function. 2) Looking at the unit circle I noticed that cos (x) =1, corresponds to 360°. in other words cos (360º) =1, the answer is x=360º or x=2π radians. 3) you can check your answer in your graphing calculator by pressing ... lim_(x->0) (cos(x)-1)/x = 0. We determine this by utilising L'hospital's Rule. To paraphrase, L'Hospital's rule states that when given a limit of the form lim_(x→a)f(x)/g(x), where f(a) and g(a) are values that cause the limit to be indeterminate (most often, if both are 0, or some form of ∞), then as long as both functions are continuous and differentiable at and in the vicinity of a, one ...
