Hi,

Can anyone explain how I can find dy/dx of the following:[

8Ye^(6XY)]=sin(4x)

Many thanks

Hi Bryn

Now do the implicit differentiation - February 6th 2010, 12:09 PMBryn
I can't seem to proceed easily,

The answer I have worked out is as follows:

(1/8y)(dy/dx)+6y+6x*(dy/dx)=(4cos(4x))/sin(4x)

Using this the question asks me to find the value of dy/dx at the coordinates (0,0).

I found this to be 0 which it seems is wrong, can someone explain to me why this is?

Many thanks
