    Further Mathematics: Post your doubts here!

    Ahhh, I got it! It would only be the cossine if the function was sin(t) then with respect to t it would be just cos(t). Since we have a theta it changes the differentiation. Thank you very much!

    Hello everyone, Could someone explain me why the marking scheme considers the tangential acceleration (in the exercise below) to be l*sin (O)*cos(O)? O= theta. I don't get where the sin(O) comes from. May/June 2009 P2 Question 1. Thank you very much!

    Hello everyone, Could someone please explain me how they got the result for the normal contact force in the second part of this question. I had no problem finding the frictional force but in the marking scheme they mention a force of m*a*(angular acceleration) acting opposite to the...

    Physics: Post your doubts here!

    Hey everyone! this question is really anoying me. The question asks us to calculate the potential difference at B when the temperature is 15 C The marking scheme says that the potential difference at B is 2.4 V but I have calculated it to be 6.6 V, using 2200*9/(2200+800). Consequently it asks...

    Hey people, I was doing a paper and dy/d(theta) appeared in the marking scheme to measure the largest distance of a polar curve from the initial line. Could anyone tell me what else is it (dy/d(theta)) used for? I know dx/d(theta) is used to find the tangents of a polar curve, but dy/dO is...

    Biology MCQ thread..!!

    first question: photosynthesis produces energy, right? so we must look to the values related to a loss of energy by the plant. These values are : used for growth 21 500 kJ used for other life processes 1 500 kJ respiratory heat losses 500 kJ. Add them up: 23500 kJ. The other values have nothing...
