    For the car question, if t=0 doesnt it mean that the equation would be 15700e^0+2300(0)=15700? not 18,000???

      t is not actually part of the equation he just highlighted it accidentally

    • @LavrientyBeria
      @LavrientyBeria 2 роки тому +57

      He accidentally highlighted the expression stating that t is apart of the real numbers. Quite poor from the examiners (if this is an actual exam question) as it's quite easy to think that t is a part of the actual equation.

    in last question part b(i) did you multiply 3925 by -0.25? i can see the (-) but what about multiply 0.25 ? or i didnt get something ?

    • @wlockhart
      @wlockhart Рік тому +2

      The 15,700 from the original function has already been multiplied by -0.25 to give -3925 in the derived function. Then the sign is taken care of due to the fact that this derivative is equal to -500 when time is T. You don't need to multiply by 0.25 or -0.25 again.

    At 12:28, why isn't he subtracting a 1 from the power when he is differentiating, shouldn't you decrease 1 from the power when differentiating(using the power rule)?

    Shouldn't the differential have +2300 since it is written as 2300t? that doesn't just vanish does it?

    • @wlockhart
      @wlockhart Рік тому +3

      I thought that at first, but there's a space between the 2300 and the t. The second t is not part of the equation, it's part of an expression t -> real numbers. It could be clearer to be honest
