What's New? As we have seen questions was generally asked from this section. Many people finds it difficult to solve this types of problem.

Trigonometry-Minimum Maximum Values

Next, plot these values and obtain the basic graphs of the sine and cosine function Figure 1. Several additional terms and factors can be added to the sine and cosine functions, which modify their shapes.

This also holds for the cosine function Figure 3. This also holds for the cosine function Figure 4. These two functions have minimum and maximum values as defined by the following formulas. What are the maximum and minimum values of the function? This also holds for the cosine function. The phase shift is D. This is a positive number. It does not matter whether the shift is to the left if D is positive or to the right if D is negative.

The sine function is odd, and the cosine function is even. In other words,. Example 3: What is the amplitude, period, phase shift, maximum, and minimum values of. It is important to understand the relationships between the sine and cosine functions and how phase shifts can alter their graphs. Previous Periodic and Symmetric Functions. Next Graphs Other Trigonometric Functions.

Trigonometry Tricks – 4 [Maximum and Minimum Values]

Periodic motions can be modelled by a trigonometric equation. By differentiating these functions we are then able to solve problems relating to maxima maximums and minima minimums. Remember that the following steps are used when solving a maximum or minimum problem. The population of a colony of ants rises and falls according to the breeding season. Note: Finding the derivatives of the functions is not always the case.

But the process to find both minimum and maximum values is same. Although differentiation is a wide topic in itself, but for CGL purpose, we only have to learn the basics. Let us solve a CGL question: Q. Note that in this question, the value of a is positive, i. Sign in.

Explanation is then given as to how the maximum and minimum values are found from an expression written in this form together with the values of x at which these points occur. The graphical solution 1 explains how to use the graphic calculator to find the coordinates of the maximum and minimum values of the given function. The function is drawn and the coordinates of the maximum and minimum points are verified. The explanation explains how to set the axes to ensure the solutions are shown on the screen.

Notice the wave shape of the graph. This is called the period. Notice the similar wave shape of the graph. Notice that the two graphs look very similar.

Today well see how to find the maximum value greatest value or the minimum value least value of a trigonometric function without using differentiation. Take a pen and note-book, keep doing the steps while reading this article. First Remember following identities:.
