(a) The voltage, V, in a circuit is given by V=3R3−135R2+1800R+200 where R is the resistance in kΩ. (i) Compute dRdV​. (3 marks) (ii) Compute R values of turning point. (3 marks) (iii) Compute whether R makes a maximum voltage or minimum voltage. (4 marks) (b) If y=x2x3+1, show that dxdy​=x2x3+1(x2x3+1​+6x2ln(x))=3 at the point x=1 by logarithmic differentiation. (10 marks)
