 Question Answer When do you use trigonometry? (sOhcAhtOa) In right angled triangles where an interior angle is involved (not the 90 degree one) and you know 2 measurements. When do you use Pythagoras? (a squared + b squared = c squared) When no angles are involved, trying to find a length. In Pythagoras where is c? Opposite the right angle. When is the sine rule used? (a/sinA = b/sinB = c/sinC) On a non-right angled triangle to find angles or sides. When is the cosine rule used? In a non-right angled triangle when the is no matching pair. What is a good way to solve a quadratic equation? (x squared+x+n=0) The quadratic formula in the front of paper. In a histogram what is the width and how do you get it? The class width = the range between each individual variable category ie-'height 0<20' would be the difference between 0 and 20. In a histogram what is the height and how do you calculate it? frequency density = freq density/class width In a histogram how do you find out the mean? Total(midpoint x freq)/total freq How do you solve an algebraic equation graphically? 1) Plot 2) state where they cross What is 'BIDMAS'? Calculate things in the order of: Brackets, Indices(powers), Division, Multiplication, Addition, Subtraction.
