Chapter 7.1, Problem 114E
DISCUSS: Equations That Are Identities You have encountered many identities in this course. Which of the following equations do you recognize as identities? For those that you think are identities, test several values of the variables to confirm that the equation is true for those variables.
- (a) (x + y)2 = x2 + 2xy + y2
- (b) x2 + y2 = 1
- (c) x(y + z) = xy + xz
- (d) t2 − cos2 t = (t − cos t)(t + cos t)
- (e) sin t + cos t = 1
- (f) x2 − tan2 x = 0
