I want to test who has dare to answer this question in brainly for each question I will give more points see the above picture

who will answer this question for points they are not real students
pls answer this question
​

Answer 1

Answer:

-1

Step-by-step explanation:

Given sin (x+y) = log (x+y)

Differentiate w.r.t.x

cos (x+y) (1 + dy/dx) = [1/(x+y)] (1 + dy/dx)

dy/dx [ cos (x+y) – 1/(x+y)] = [1/(x+y) – cos (x+y)]

dy/dx = [1/(x+y) – cos (x+y)]/[ cos (x+y) – 1/(x+y)]

dy/dx = -1

Hope it helps..!!

Plz Mark as Brainliest..!!
