Sin Graph
Trigonometric graphs - HigherThis circle has the centre at the origin and a radius of 1 unit.The point P can move around the circumference of the circle. At point P the -coordinate is and the -coordinate is.As the point P moves anticlockwise around the circle from 0°, the angle changes.The values of and also change.The graphs of and can be plotted. The graph of y = sin θThe graph of has a maximum value of 1 and a minimum value of -1.The graph has a period of 360°. This means that it repeats itself every 360°. The graph of y = cos θThe graph of has a maximum value of 1 and a minimum value of -1.The graph has a period of 360°. The graph of y = tan θAs the point P moves anticlockwise round the circle, the values of and change, therefore the value of will change.This graph has a period of 180°. Calculating angles from trigonometric graphsThe symmetrical and periodic properties of the trigonometric graphs will give an number of solutions to any trigonometric equation.
ExampleSolve the equation for all values of between.Using a calculator gives one solution:Draw the horizontal line.The line crosses the graph of four times in the interval so there are four solutions.There is a line of symmetry at, so there is a solution at.The period is 360° so to find the next solutions subtract 360°.The solutions to the equation are:= -330°, -210°, 30° and 150°. QuestionSolve the equation for all values of between. West bend poppery ii instructions. Give your answer to the nearest degree. Reveal answer.
How To Graph Tangent Functions
Do you see that this second graph is three times as tall as was the first graph? The amplitude has changed from 1 in the first graph to 3 in the second, just as the multiplier in front of the sine changed from 1 to 3.
