Question
In Exercises 19-26, (a) find dy, and (b) evaluate dy for the given
value of x and dx.
19. y = x – 3x, x= 2, dx = 0.05
2x
20. y =
1+x²'
x = -2, dx = 0.1
21. y = x2 In x, x= 1, dx = 0.01
22. y = xV1 - x², x= 0, dx = -0.2
23. y = en, *= T, dx = -0.1
24. y = 3 csc
x = 1, dx = 0.1
25. у + ху — х 0, х 0, dx%3D 0.01
26. 2y = x? – xy, x= 2, dx = -0.05
