2.3 make connections between the sine ratio and the sine function and between the cosine ratio and the cosine function by graphing the relationship between angles from 0[degree sign] to 360[degree sign] and the corresponding sine ratios or cosine ratios, with or without technology (e.g., by generating a table of values using a calculator; by unwrapping the unit circle), defining this ...

for the cosine (one underline), yet we have two pieces of information for the. tangent (two underlines). We are therefore going to use the tangent ratio formula: Step 6 : Substitute the known information into the formula: Step 7: Solve for x. In this example, it is probably simplest to multiply both. sides by 28: Step 8: Simplify. You may use a handheld calculator (in degrees mode) to ...

Other words teachers found important are: similar, ratio, function, angle, length, sine, cosine, tangent, inverse sine etc., multiplier, scale; accuracy, equality, horizontal, vertical, compare, trigonometric, elevation, depression. One teacher said they would not use names for ratios in the first lesson but would explore their meaning and use and name them later. Two teachers emphasised ...
