    (a) d dt y7=7Y^6

    (b) d dt y3e4t=3Y^2e^{4t}+4Y^3e^{4t}

    (c) d dt t7 cos (y6) = 7t^6 cos (y6) + t^7 (-sin (y^6)) ·6Y^5

    Step-by-step explanation:

    We calculate the following derivatives. Since these are complex derivatives, we also calculate the formula for complex derivatives. We use Y for the derivative of y. Therefore, we calculate and we get

    (a) d dt y7=7Y^6

    (b) d dt y3e4t=3Y^2e^{4t}+4Y^3e^{4t}

    (c) d dt t7 cos (y6) = 7t^6 cos (y6) + t^7 (-sin (y^6)) ·6Y^5
