Question

Find the derivative of:
sin(xy)=2x+5 Find the derivative of:
sin(xy)=2x+5 @Calculus1

Answer 1

differentiating with respect to x.
d(sin xy)
------ = y cos (xy) so
dx

your answer is:
y cos (xy) = 2

Answer 2

I already got the answer but that is totally wrong

Answer 3

The product rule needs to be used and you didn't use it properly

Answer 4

Yes I used!

if y = sin u

y' = u' cos u , as I said before.
