EDEXCEL GCSE MATHS EXAM QUESTIONS AND ANSWERS WITH COMPLETE SOLUTIONS VERIFIED Practice questions for this set Terms in this set (77) Equation of a straight line y = mx + c y = gradient + starting point Boxplots A pictorial display that indicates the range, median, and interquartile range Trigonometric graphs using sine Find sine using sine cosine. Then, measure how far the original is to one of the big numbers (90, 180, 270). Then have that same difference on the opposite side. Trigonometric graphs using cosine Find cosine using cosine minus. Then, measure how far the original is to one of the big numbers (90, 180, 270). Then have that same difference on the opposite side. F Finding cos (non- calculator) To find the cos, you count how many fingers are on the left. Trigonometry The branch of mathematics dealing with the relations of the sides and angles of triangles and with the relevant functions of any angles. Uses sin, cos and tan Finding sin (non- calculator) Count the fingers on the left and square root the number of fingers. Then, divide by 2. SOHCAHTOA Used to work out triangles using trigonometry. Trigonometric graphs using tangent Work out the tan using tan minus on the calculator. Then, add the answer to 180 degrees. Write both answers down. Equation of circle The equation of any circle where the centre is at the origin is given by x^2 + y^2 = r^2 Ratio "The ratio of almonds to cashews is 2:3. The ratio of cashews to peanuts is 5:8. Calculate the number of cashews in the box." a : c : p 2 : 3 x 5 5 : 8 x 3 10 : 15 : 24 10+15+24 = 49 1372 / 49 = 28 28 x 15 (cashews) = 420 cashews
