How do you define a Trigonometric Function?

In trigonometric ratios, we have studied trigonometric ratios for acute angles as the ratio of sides of a right-angled triangle. We will now extend the definition of trigonometric ratios to any angle in terms of radian measure and study them as trigonometric functions. Let’s take a xy plane & draw a circle with radius (PO) 1 cm & center as center of xy plane. Since one complete revolution subtends an angle of 2π radian at the centre of circle, ∠AOB = π/2, ∠AOC = π and ∠AOD = 3π/2. All angles which are integral multiples of π/2 are called quadrantal angles. Let us name these quadrants as Quadrant I, II, III & IV.
