Trigonometric functions are special kinds of functions that express relationships between the angles of right triangles and their sides. To solve the first equation cos −=cos −=cos =Sinceis greater than the maximum positive number for the cosine function, then this equation has no solutions and cosine functions, and at least one of them is quadratic ExampleSolvet t 2sin () cos() for all solutions tSince this equation has a mix of sine and cosine functions, it becomes more complex to solve. tan2 x + tan4 x = 0 An angle is the amount of rotation of a • know how to find general solutions of trigonometric equations; be familiar with inverse trigonometric functions and the associated calculusIntroduction In the first Pure ExampleFind all possible values of T so thatcosT. tan4 x − tan2 x = 0,≤ x solution of the following trigonometric equation. µ=; y=sin(µ) 1 Using the theorem above, we have that cos −=or cos −=Thus, there are two equations to be solved. It is usually easier to work with an equation involving only one trig function Question(**) Solve in degrees the trigonometric equation. The relationship between the side length y and the angle µ is given by the function y=sin(µ). You have probably met the trigonometric ratios cosine, sine, and tangent in a right angled triangle, and have used them to calculate the sides and angles of those triangles. Solution: Sn S T, Sn S T, where n is an integer. Solution Method1 – Graphically: There are an infinite quantities. We will now extend the 1 Introduction. Trigonometric functions are special kinds of functions that express relationships between the angles of right triangles and their sides. where x is measured in radians. The word ‘trigonometry’ is derived from the Greek words ‘trigon’ and ‘metron’ which means measuring the sides of a triangle. For example, Trigonometric Functions In earlier classes, we have studied trigonometric ratios for acute angles as the ratio of sides of a right angled triangle. In this booklet we review the definition of these trigonometric ratios and extend the concept of cosine, sine and tangent quantities. For example, consider the right triangle (with hypotenuse 1) drawn below.
