Unformatted text preview: angle of elevation of the Sun. The length of the shadow s is related to the angle of elevation of the Sun, θ , by the formula cot 20 = s . Find the rate at which the length of the shadow is changing with respect to when is 45 o . [Source: “Calculus: Early Transcendentals”, 8 th ed. by H. Anton, I. Bivens, and S. Davis, 2005] Finally, we can use the trig limits we introduced earlier to help us compute other trigonometric limits.
