(sec x - tanx)^2 = (1-sinx)/(1+sinx) use these substitutions sin²(x) + cos²(x) = 1 cos²(x) = 1 - sin²(x) (sec(x) - tan(x))² =(1/cos(x) - sin(x)/cos(x))² = (1-sin(x))² / cos²(x) = (1-sin(x))² / (1 - sin²(x)) = (1-sin(x))² / [(1+sin(x))(1-sin(x))]
Let Mary=Y Peter=X Mary is 2/3 Peter's age therefore: Y =2/3X two years ago..mary was 1/2 peter's age in 5 years..we write the equation as: (Y) -2 = 1/2(x+5) substitute Y=2/3X 2/3X - 2 = 1/2x + 5/2 solve for X X=27.....therefore Y=18
