In this series of tutorials I show you several examples of how to solve trig. equations in a given range which equal 0 and factorise. You are shown how to use the quadrant method in the final part.. To see the full revision guide goto ExamSolutions at http://www.examsolutions.co.uk/maths-tutorials/Core-maths/trigonometry/equati...
If the range was big enough would -236.3 be an angle?
By using the cast diagram but backwards (in the negative direction)...
Thanks for the great vid btw,
