2.6 Exercises > 1-4 9. (a) Find y' by implicit differentiation. = y- +1 10. y' +xy'= ltxty xty (b) Solve the equation explicitly for y and differentiate to get y' in terms of x. 11. sin x + cosy = 2x - 3y 12. y sin(x-) = x sin(y!) (c) Check that your solutions to parts (a) and (b) are consistent by substituting the expression for y into your solution for 13. sin(x + y) = cos x + cos y 14. tan(x - y) = 2xy' + 1 part (a). 15. tan(x/y) = x + y 16. sin(xy) = cos(x + y) 1. 5x - y' = 7 2. 6x* + y = 2x 4. 2 17.
