You buy a bond that matures at par in one year. It has an even value of $ 100 and pays 4% convertible coupons semi-annually. The price paid to guarantee a semi-annual convertible rate j is $ 98.51. Calculate j using the following methods: a) Taylor of the second degree b) Bond Salesman c) Newton-Raphson (3 iterations, take 3% as initial solution)

Note: "matures at par in one year", it means only 2 semesters to go. Take as initial solution for N-R an i = 3%.
