    In that case, you can derive it by creating a truth table with T and Q as inputs and make the output the same as the JK flip flop's., then simplify.

    A JK F/F will toggle states with the clock when you set J=K=1.

    For the minute, the definition of a T flip-flop eludes me - but a D flip-flop will toggle on each relevant clock edge if you connect the NOT-Q output back to the D input.

    The definition of a T flip-flop is
    when T input = 0, Q output remains unchanged with the next clock pulse
    when T input = 1, Q = Q' with the next clock pulse.

    Connecting Q' to the D input of a D flip-flop creates the second functional part of the T flip-flop.
