Trigonometric Functions Class 11 Formulae & Notes are cumulated in a systematic manner which gets rid of confusion among children regarding the course content since CBSE keeps on updating the course every year. The formulae list covers all formulae which provides the students a simple way to study of revise the chapter. T Trigonometric Functions Class 11 Formulae & Notes would provide you with an effective preparation for your examinations.
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.Learn more about the same in Trigonometric Functions Class 11 Formulae & Notes pdf.Download this solution for FREE.
