Question

What is the derivative of ln(y)sin(x)

Answer 1

You are going to have to use some implicit differentiation and the product rule here! So, let's just do that:

`(d)/(dx)[ln(y)sin(x)]`

Is equal to:

`( (1)/(x)* (dy)/(dx)*sin(x)) -`

`((sin(x))/(x) * (dy)/(dx)) - (ln(y)cos(x))`
Or:


That's your answer! Hope this helps, if anything doesn't make sense, hmu!
