WebThe set composed of rational and irrational numbers is called the real numbers. Given any two real numbers a and b, it is always possible to state that Many times we are only interested in whether or not two numbers are equal, but there are situations where we also wish to represent the relative size of numbers that are not equal. WebAs we saw with integers, the real numbers can be divided into three subsets: negative real numbers, zero, and positive real numbers. Each subset includes fractions, decimals, and irrational numbers according to their algebraic sign (+ or –). Zero is considered neither positive nor negative.

WebMar 24, 2016 · pi/6, pi/2, (5pi)/6 f(x) = 2sin^2 x - 3sin x + 1 = 0. Solve this quadratic equation for sin x. Since a + b + c = 0, use shortcut. The 2 real roots are: sin x = 1 and sin x = c/a = 1/2. a. sin x = 1 --> x = pi/2 b. sin x = 1/2. The trig unit circle gives 2 arcs that have the same sin value (1/2) x = pi/6 and x = pi - pi/6 = (5pi)/6
