Question

differentiate [3sin 2x = xy]

Answer 1

implicit differentiation will give you 6 sin(2x) = y'

Answer 2

6sin 2x or 6 cos 2x??

Answer 3

6cos(2x) sorry :))))

Answer 4

implicit (xy)
means that..
x dy/dx (y) + y dy/dx (x)

Answer 5

ok...let me rephrase my answer..[.6 cos(2x) - (3sin(2x))/x]/x

simplified even further...

[6x cos(2x) - 3sin(2x)]/x^2

i really am sorry for the mistakes...i have forgotten this lesson...
