Discover a time t at which the prompt pace is the same as the common pace for the complete journey. 22. the peak (in meters) of a helicopter at time t (in mins) is s(t) = 600t − 3t three for zero ≤ t ≤ 12. (a) Plot s(t) and pace v(t). (b) locate the speed at t = eight and t = 10. (c) locate the utmost top of the helicopter. 23. A particle relocating alongside a line has place s(t) = t four − 18t 2 m at time t seconds. At which instances does the particle go through the foundation? At which occasions is the particle right away immobile (that is, it has 0 velocity)?

Plot the graph of f (x) = x/(4 − x) in a viewing rectangle that sincerely screens the vertical and horizontal asymptotes. 20. locate the utmost worth of f (θ) for the graphs produced in workout 19. are you able to bet the formulation for the utmost price by way of A and B? 10. Illustrate neighborhood linearity for f (x) = x 2 by means of zooming in at the graph at x = zero. five (see instance 6). 21. locate the durations on which f (x) = x(x + 2)(x − three) is confident through plotting a graph. eleven. Plot f (x) = cos(x 2 ) sin x for zero ≤ x ≤ 2π. Then illustrate neighborhood linearity at x = three.

X→1 28. end up carefully that lim sin x1 doesn't exist. x→0 29. First, use the id if zero < |x − 2| < δ (c) discover a δ > zero such that x1 − 12 < zero. 01 if zero < |x − 2| < δ. 1 1 (d) end up carefully that lim = . 2 x→2 x √ 14. give some thought to lim x + three. x→1 sixteen. Adapt the argument in instance 1 to end up carefully that lim (ax + b) = ac + b, the place a, b, c are arbitrary. x→c √ nine. Plot f (x) = 2x − 1 including the horizontal traces y√= 2. nine and y = three. 1. Use this plot to discover a price of δ > zero such that | 2x − 1 − three| < zero.

For this reason, we may well count on the slopes of the secant traces to process the slope of the tangent line. according to this instinct, we outline the by-product f (a) (which is learn “f best of a”) because the restrict f (a) = lim x→a f (x) − f (a) x−a restrict of slopes of secant traces a hundred and twenty Definition of the spinoff S E C T I O N three. 1 y y y 121 y Q Q Q Q P P x x a x a x (B) (A) determine 2 The secant traces method the tangent line as Q methods P . P P a (C) x x a (D) x x there's otherwise of writing the adaptation quotient utilizing a brand new variable h: h=x−a we have now x = a + h and, for x = a (Figure 3), y Q f (a + h) − f (a) f (x) − f (a) f (a + h) − f (a) = x−a h The variable h ways zero as x → a, so one can rewrite the by-product as P h a x=a+h x determine three the variation quotient may be written when it comes to h.

28. t→∞ (4t 2/3 + 1)2 |x| + x x→−∞ x + 1 lim 30. x three + 20x x→∞ 10x − 2 lim 4x − three lim x→−∞ lim 25x 2 + 4x t 4/3 − 9t 0.33 t→∞ (8t four + 2)1/3 four + 6e2t t→−∞ five − 9e3t lim verify lim tan−1 x. clarify geometrically. x→∞ 32. exhibit that lim ( x 2 + 1 − x) = zero. trace: realize that x→∞ x2 + 1 − x = 1 x2 + 1 + x R(s) = As okay +s (A, ok constants) (a) exhibit, by means of computing lim R(s), is the proscribing response cost s→∞ because the focus s ways ∞. (b) convey that the response fee R(s) attains one-half of the proscribing worth A while s = ok.
