what is the yield to maturity on a 7 year bond that has a par value of $1000 it is currently selling at $920.56 and pays a 5% coupon semi annually? show your work please 4.04% 6.45% 6.42% 4.03%

Solution

first sqrt(2)/2 can be written as 1/sqrt(2)

so the point is (-1/sqrt(2) , -1/sqrt(2) )

hypotenuse = sqrt[ (-1/sqrt(2) )^2 + (-1/sqrt(2) )^2 ]

hypotenuse = sqrt [ 1/2 +1/2 ]

=1

so now sin = y/ hypotenuse

  sin = -1/sqrt(2)

cos= x/ hypotenuse

cos = -1/sqrt(2)

tan= y/x

tan= 1

csc=1/sin

csc = -sqrt(2)

sec= 1/cos

sec = -sqrt(2)

cot =1/tan

cot=1
