What is the derivative of sin(3x+1)^4?

  • Calculus -

    let y = sin (3x+1)^4

    dy/dx = cos (3x+1)^4 * 4(3x+1)^3 * 3
    = 12(3x+1)^3 cos (3x+1)^4

    I took the problem exactly the way you typed it.

    another interpretation would be

    (sin (3x+1) )^4 , but needing the brackets as shown
