= (x+3)^6 * (3(2x-5)^2*2) + (2x-5)^3 * (6(x+3)^5) = (x+3)^6 *(6(2x-5)^2) + (2x-5)^3 * (6(x+3)^5) = 6(x+3)^6 (2x-5)^2+ 6(2x-5) (x+3)^5 factoring this part is where I get stuck ?

hi sorry about the mistakes, the question is differentiate , y = (2x-5)^3 (x+3)^6 I can get up to where you have to factor the equation, but am unsure what to do from there , any help would be much appreciated ??

Homework Statement [/B] hi could some body please help me factorise this please ? any chance of a few stages would be much appreciated Homework EquationsThe Attempt at a Solution my attempt , but my solutions say otherwise ? [/B]

hi thanks for the advice every one, 0.01 is in the equation because the first measurement of the magnetic field was measured 10 mm away from the centre of the single loop coil, is this equation correct ?

thanks again, I might seem stupid, I have only done physics since Christmas , I can't see how there is only a 0.003 voltage difference ?

thanks, but i missed something out the question, the equation is for single-loop coil

Homework Statement this is the equation for flux density we have been given, the radius 30mm, z= goes in stages of 10mm, from zero to 50mm, then from zero to -50mm. that symbol at the begin of equation is 4 pie ! and the current is 5 amps. its is for a single-loop coil Homework EquationsThe...
