WebExamples Using Cosine. Example 1: Determine the value of the length of the base of a right-angled triangle if cos x = 0.8 and the length of the hypotenuse is 5 units using cosine function formula. Solution: We know that cos x = Base/Hypotenuse. We have cos x = 0.8, Hypotenuse = 5 units. Therefore, 0.8 = Base/5. Web1. An easy way to find the vertical shift is to find the average of the maximum and the minimum. For cosine that is zero, but for your graph it is − 1 + 3 2 = 1. Therefore the vertical shift, d, is 1. Notice that the amplitude is the maximum minus the average (or the average minus the minimum: the same thing). pinstame https://elyondigital.com
