the Y axis 1 4. Ay Calculate the slopes of curves and solve for the equation of the tangent line and 4AX normal line to a curve. 2-43. If Ay = 2y1 + Ay and y is 2-38. The slope of a curve at a point, independent of both Ax and Ay, P(x , y) , can be represented by sy then as Ax approaches zero Ay approaches a value of 1. True 1. zero 06 230) ON2 09 2. False 2 . 2-39. Which of the following statements 4 is TRUE regarding the error 3 . 241 + By incurred in calculating the slope of a curve at a given point? 4 . 241 1. Calculation error is small if the curvature is great and large increments of 4y and AX 2-44. If the slope of the tangent line are used to a curve at the point (5, 10) 2. Calculation error is large if is 3/2, the equation of the tan- the curve is nearly flat, gent line is nolsauge and? .85-5 regardless of the value of the Ax and Ay increments 1. 2x - 3y + 10 = 0 3.
