Web2.3 Trigonometry. Welcome to this short ‘insights video’ showing some of the misunderstandings learners have when solving questions with trigonometric quadratic, or cubic, equations. Solving ‘trigonometric’ quadratic equations uses the same techniques as ordinary quadratic equations, for example, factorising. WebThe various trigonometric formulae and identities can be used to help solve trigonometric equations. Here is a summary of the most important trigonometric formulae you should know: sin 2 x + cos 2 x = 1 1 + cot 2 x = cosec 2 x tan 2 x + 1 = sec 2 x cos2x = cos 2 x - sin 2 x = 2cos 2 x - 1 = 1 - 2sin 2 x sin2x = 2sinx cosx tanx = sinx cosx
