As we know, tan is the ratio of sin and cos, such as tan θ = sin θ/cos θ. cos 90° Putting values = 1 × √3/2 × 1/√2 × 1/2 × 0 = 0 . It can be seen that the value of the sine and cosine function does not change if the x and y values are the integral multiples of π/2. Since this is a periodic function, cosine of x equals zero at these intervals on the unit circle, a circle of radius one that lies on the origin of the x-y axis. In fact, the functions sin and cos can be defined for all complex numbers in terms of the exponential function via power series or as solutions to differential equations given particular initial values (see below), without reference to any geometric notions.
