I dont believe you typed the whole equation, if you can clarify I might be able to help! but 3×27 = 81 if that's what you were looking for.
Did you ever get the answers to this quiz
Cofunctions in trigonometry are function pairs like sine and cosine
Examples:
sin(π/2 - x) = cos(x), cos(π/2 - x) = sin(x), tan(π/2 - x) = cot(x), and cot(π/2 - x) = tan(x)
Purpose:
The cofunction identities show the relationship between sine, cosine, tangent, cotangent, secant, and cosecant. The value of an angle's trig function equals the value of the angle's complement's cofunction
Answer:
current market price of the bond is $958.73
Step-by-step explanation:
given data
coupon rate = 5.74 percent
yield to maturity = 6.1 percent
bond matures = 20 years
future value = $1,000
solution
we get here PMT that is
PMT = 1,000 × 5.74% ÷ 2 ...............1
PMT = $28.70
and Number of Periods is
NPER = 20 years × 2 = 40 semi-annual periods
and here Rate of interest will be = 6.1% ÷ 2 = 3.05%
and we use here formula that is
= -PV(Rate;NPER;PMT;FV;type)
so we get
current market price of the bond is $958.73
