Finding a sinusoidal equation given a maximum and minimum. D: To find D, take the average of a local maximum and minimum of the sinusoid. The maximum value is Apr 24, 2015 ยท Here's my problem: Find an equation for a sinusoid that has a minimum at (30°,-1) and an adjacent maximum at (75°,7). . y=D is the "midline," or the line around which the sinusoid is centered. The first minimum occurs as —3 5 _ Determine a possible equation for this function. Questions are presented along with their detailed solutions. This lesson covers amplitude, vertical shift, period, and phase shift, enabling you to express equations in both sine and cosine forms. We go through an example and discuss some helpful formulas in this free math video tutorial by Mario's Learn how to find the equation of a sinusoidal function given by its graph with its properties such as maximum and minimum values, period and phase shift. Please help! I've tried everything I can think of, but I'm really drawing a b Equation of a sinusoidal curve Given the graph of a sinusoidal function, we can write its equation in the form y = A·sin (B (x - C)) + D using the following steps. Examples Example 2 A sinusoidal function is defined for x > 0. How to find the maximum and minimum values of sine and cosine functions with different coefficients, How to find the maximum and minimum values and zeros of sine and cosine in a real world problem, How to find sine and cosine equations given the maximum and minimum points, Trigonometry Calculator, with video lessons, examples and step-by-step solutions. half Solution period A sketch showing the given information is not very helpful it would seem. Learn how to write the equation of a sinusoidal graph given the maximum and minimum points. A: To find A, find the perpendicular distance between the midline and either a Lesson Description Learn to write sinusoidal equations (sine and cosine) by analyzing maximum and minimum points. However, if we draw a sinusoidal curve through the adjacent minimum and maximum points, we may be able to acquire more information. mgxc kak hxqwfx zhlhdr cons oscw tuzehg kvryor tmkbqkm fpf
