Question
![[B] A loan of $210000 is repaid over 20 years by monthly payments of $1575. Use two iterations of the
Newton-Raphson method starting with the initial guess of an annual interest rate of 12% (compounded
monthly), to determine the annual interest rate.
NOTE: IfP is borrowed at a rate of r per period, and is repaid over N periods by payments of Y, then:
Pr + Y[(1+r)-N – 1] = 0
If f(r) = 210000r + 1575[(1+r) 400 – 1] and f'(r) = k – a(1+ br)-€, then:
k
