This video by TeacherLookup explains ways to remember trigonometric functions. It starts with a brief introduction on different trigonometric functions and how they are used to calculate angles and sides of a triangle. It explains some of the common trigonometric functions as listed below: Sin A Cos A Tan A Cosec A Sec A Cot A It has then listed out some common formula that reveal the relationship between the above terms with the Help of a triangle diagram. It shows that: Sin A =opposite/hypotenuse Cos A = adjacent/ hypotenuse Tan A= sin A /cos A = opposite / adjacent Please click on this link to take you to the page shown on video: teacherlookup.com/learn-how-to-remember-trigonometric-functions
