Hi,
Please provide some inputs.
1) A Zero Coupon Bond with a maturity of 10 years has an annual effective yield of 10%.
2) Different Discounting Methods
Consider a bond that pays $100 in 10 years and has present value of $ 55.8395. This corresponds to an annally compounded rate of 6%. This rate can be transformed into a semi-annual compounded rate.
2 
It can be also transformed into a continuously compounded rate = 5.83%
3) Another requirement is to increase the frequency of the compounding, the resulting rate decreases.
