WebFor cos pi, the angle pi lies on the negative x-axis. Thus, cos pi value = -1 Since the cosine function is a periodic function, we can represent cos pi as, cos pi = cos(pi + n × 2pi), n ∈ Z. ⇒ cos pi = cos 3pi = cos 5pi , and so on. Note: Since, cosine is an even function, the value of cos(-pi) = cos(pi). jeep sertaozinho
