Draw European Article Number 13 In ObjectiveC Using Barcode drawer for iPad Control to generate, create EAN13 image in iPad applications. and r = t where t is the parameter on which both q and r depend How can we sketch a polar graph of this system Make Data Matrix ECC200 In ObjectiveC Using Barcode creator for iPhone Control to generate, create Data Matrix image in iPhone applications. Encode Code128 In None Using Barcode encoder for Word Control to generate, create Code 128C image in Microsoft Word applications. Answer 164 We can input various values of t, restricting ourselves to values such that we see only the part of the graph corresponding to the first full counterclockwise rotation of the direction angle, where 0 q 2p: When t = 0, we have q = 3 0 = 0 and r = 1 0 = 0 When t = p /4, we have q = 3p /4 and r = p /4 079 When t = p /2, we have q = 3p /2 and r = p /2 157 When t = 2p /3, we have q = 3 2p /3 = 2p and r = 2p /3 209 Figure 2010 illustrates this graph, based on these four points and the intuitive knowledge that the graph must be a spiral, starting at the origin and expanding as we rotate counterclockwise The graph is a little tricky, because all of the radii are negative! Also, we should remember that the concentric circles represent radial divisions on the polar coordinate grid; the straight lines represent angular divisions Figure 2010 Illustration for Question and Answer 164 In this coordinate system, each radial division represents p /4 units Part Two 423 Question 165 Consider again the pair of parametric equations q = 3t and r = t How can we use algebra to determine the equivalent equation in terms of q and r only Answer 165 The equation can be derived using the same algebraic process that we used in the Cartesian situation We substitute q in place of x, and we substitute r in place of y When we do that, we get r = ( 1/3)q Question 166 What are the parametric equations for a circle centered at the origin in the Cartesian xy plane
Answer 166 The parametric equations are x = a cos t and y = a sin t where a is the radius of the circle and t is the parameter Question 167 What are the parametric equations for a circle centered at the origin in the polar coordinate plane
Answer 167 Let the polar direction angle be q, and let the polar radius be r The parametric equations of a circle having radius a, and centered at the origin, are q=t and r=a where t is the parameter Review Questions and Answers Question 168 Why does only one of the equations in Answer 167 contain the parameter t Shouldn t both equations contain it Answer 168 The parameter t has no effect in the second equation, because the polar radius r of a circle centered at the origin is always the same, no matter how anything else varies Question 169 What are the parametric equations for an ellipse centered at the origin in the Cartesian xy plane
Answer 169 The parametric equations are x = a cos t and y = b sin t where a is the length of the horizontal (xcoordinate) semiaxis, b is the length of the vertical (ycoordinate) semiaxis, and t is the parameter Question 1610 Why is the passage of time a common parameter in science and engineering
Answer 1610 In the physical world, many effects and phenomena depend on elapsed time If we find time acting as a mathematical variable, then that variable is almost always independent We often come across situations where two or more factors fluctuate with the passage of time An example is the variation of temperature, humidity, and barometric pressure versus time in a specific location In a situation of this sort, time can be considered as the parameter on which the other three physical variables depend
