WebThe value of cos pi is -1. Cos pi can also be expressed using the equivalent of the given angle (pi) in degrees (180°). We know, using radian to degree conversion, θ in degrees = θ in radians × (180°/ pi) ⇒ pi radians = pi × (180°/pi) = 180° or 180 degrees ∴ cos pi = cos π = cos (180°) = -1 Explanation: WebIf you look in the picture above, it is clear that cos θ is a positive number. If π / 2 < θ < 3 π / 2 cos θ is negative, because its length is in fact negative as the line representing cos is left of the y axis. If you are familiar with radians, π is 180 degrees.
