2.y + Ay = 0.7 x + 0.7 Ax + 2. y = 0.7 x + 2. Ay = 0.7 Ax. Ay dy dx 0.7. Now 0.7 is the approximate natural tangent of 350.Hence by differentiating thefunction y = 0.7 x + 2 wehave not only found theratio of the increase of theordinate to the abscissaat any moment, but also thegradient of the line… … Fig. 8. x88 Elementary Calculus. Art. ii. The gradient of a curve. Suppose we have two bodies, Bt and B2, travelling inparallel paths, the former with an accelerated velocity of 2 ft.per second per second and the latter with a uniform velocityof 2 ft. per second. Further, imagine that Bx starts…
