What is the 2nd derivative of y=cosh(x+y)?

The derivative of y = 3cos(8x+6) is: 1. y' = 24 sin (8x+6) 2. y' = -24 sin (8x+6) 3. y' = -24 cos (8x+6) 4. y' = 24 cos (8x+6)

Get the first order derivative of the function x + sin(y – 2x) – 1 = 0. a. y' = 1 - 2 cos(y-2x) 1 b. y' = -- +2 cos(y-2x) 2 c. y' = -1-: cos(y-2x) 1+2 cos(y-2x) d. y' = cos(y-2x)
