Amplitude is first, then sine or cosine, then B, which you get by doing 2pi/10 (period), which reduces to pi/5, then it is the parenthesis with the transformation, and then last but not least is the sinusodial axis. Title: Applications of Sine and Cosine Graphs Standard(s): MA3A3. The cosine and sine functions are used in the area of simple harmonic motion because of how the oscillatory motion of an object will resemble the graphs of the trigonometric functions. This is exactly the reason why, when the graphs are plotted on grids as above, the cosine graph is equivalent to the sine graph, omitting the fact that it is shifted, or translated, 90° to the left.Additionally, this is how the name ‘cosine’ appeared; the … A French scientist and mathematician by the name of Jean Baptiste Fourier proved that any waveform that repeats Sec 5.2 Practice Worksheet More Graphing Trigonometric Functions Worksheet Answers Sec 5.3 The Tangent and Cotangent Functions Sec 5.4 Part 1 : Solving Trigonometric Equations Sec 5.4 Part 2 : Applications of Trigonometric Functions Modelling Real Life Situations Worksheet with key Review Worksheet and Review Answers Quiz #2 Trigonometry To download/print, click on pop-out icon or print icon to worksheet to print or download.
