(-exp(-2*y))/2 - y
Detail solution
  1. Differentiate y+(1)e2y2- y + \frac{\left(-1\right) e^{- 2 y}}{2} term by term:

    1. The derivative of a constant times a function is the constant times the derivative of the function.

      1. The derivative of a constant times a function is the constant times the derivative of the function.

        1. Let u=2yu = - 2 y.

        2. The derivative of eue^{u} is itself.

        3. Then, apply the chain rule. Multiply by ddy(2y)\frac{d}{d y} \left(- 2 y\right):

          1. The derivative of a constant times a function is the constant times the derivative of the function.

            1. Apply the power rule: yy goes to 11

            So, the result is: 2-2

          The result of the chain rule is:

          2e2y- 2 e^{- 2 y}

        So, the result is: 2e2y2 e^{- 2 y}

      So, the result is: e2ye^{- 2 y}

    2. The derivative of a constant times a function is the constant times the derivative of the function.

      1. Apply the power rule: yy goes to 11

      So, the result is: 1-1

    The result is: 1+e2y-1 + e^{- 2 y}


The answer is:

1+e2y-1 + e^{- 2 y}
