h) f (x) = ex+e−x , (use substitution with u = ex + e−x) i) f (x) = x ln(x2/3), (use integration by parts) l) f (x) = x ln(x2/3), (use integration by parts) 3) (3 points) Find whether each of these limits exists. If it does, find its value.
4) (2 points) For the function f (x) = x2−4 , find f (x) and f (3).
Find the equation of the tangent line to the graph of f at x0 = 1.
6) The following graph describes the height y of a rocket depending on the time tin seconds during the first four seconds. What is the average speed of the rocketduring the first three seconds? What is the instantaneous speed of the rocket after2 second? 7) (3 points) Find the slope of the curve given by the equation 8) (4 points) Below the graph of the equation is displayed. Draw the tangent for the curve at the point (0, 0.5), and use implicitdifferentiation to find the slope of that tangent line. Find also all horizontal and allverticeal tangents to the curve.
9) (4 points) A plane, flying horizontally at an altitude of 1 mile and a speed of500 miles/hour passes directly over a radar station. Find the rate at which thedistance from the plane to the station is increasing when it is 2 miles (measured onthe ground) away from the station. (Note: Of course, Pythagoras’ Theorem must beapplied again.) 10) (3 points) Find all critical points, and all the relative minimum or maximumpoints of the function 11) (4 points) Determine the intervals where the function is increasing, decreasing, concave up and concave down. (Hint: To check your work,graph the function and have a good look at it.) 12) (4 points) Determine where the function is increasing, decreasing, concave up and concave down.
13) (4 points) Find all relative extreme points (minima and maxima) of the functionf (x) = (x − 1)1/3. Where is the function increasing, where decreasing, where is itconcave up, where is it concave down? 22) (4 points) An open box with a square base should be constructed. The materialfor the bottom of the box costs 5 Sfr per square meter, and the material for the sidescosts 2 Sfr per square meter. We want to create a box with maximum possiblevolume, given that we have 400 Sfr to spend. What are the dimensions of the box? 23) (4 points) A fence 8 ft tall runs parallel to a tall building at a distance of 4 ftfrom the building. A ladder starts outside, leans on the fence, and goes just to thewall. Express the height of the highest position of the ladder (where it leans againstthe wall) in terms of the length x of the ladder. Graph the function as well.
24) (3 points) A cylindrical can with no top has beem made from 8π square inchesof metal. Express the volume of the can as a function of its radius. (Note that thevolume of the can equals area of the bottom times height.) (3 points) 25) (4 points) Given is the graph of a function f below. Roughly sketch its tangentat x = 2, the first and second derivative, f and f , and some antiderivative F .

39) (6 points) A rocket is shot vertically into air. Its height x seconds after the startcan be expressed by the function h(x) = 90x − 3x2. The temperature y at height u 15u (in degrees celsius) on that summer day.
a) What is the height of the rocket 10 seconds after start?b) What is the average speed of the rocket during the first 10 seconds?c) What is the instantaneous speed of the rocket after 10 seconds?d) What is the instantaneous acceleration of the rocket after 10 seconds?e) What is the temperature at the rocket 10 seconds after start”?f) What is the instantaneous rate of change of temperature at the rocket 10 40) (4 points) Which of the statements below is true, which one is false. If it is false,briefly explain why it is false. If you think there is a typo in any of the formulas,correct it.
a) If a function is concave up at a, then f (a) > 0.

Eskalering för MÄN, att gå från 0-100 när du möter en kvinna. Det finns en viss del inom raggning som många har problem med, och det är den så kallade eskaleringen, med andra ord: Hur går man från att först träffa en tjej till att få det att bli någonting mer än bara en vänskapligt möte? Och svaret är: en eskalering både på det mentala, verbala och fysiska planet efter just
