Cos pi/2: 0; Cos (-pi/2): 0; Cos pi/2 in degrees: cos (90°) What is the Value of Cos pi/2? The value of cos pi/2 is 0. Cos pi/2 can also be expressed using the equivalent of the given angle (pi/2) in degrees (90°).
WebIt is also true that cos (½π-x) = sin (x) and that cos (x- ½π) = sin (x) So, cos (½π-x) = cos (x- ½π) Sine and cosine are both periodic functions that are identical except for being shifted ½π radians out of phase. Thus, there are a number of ways you can shift them around to be in phase and therefore equal. WebMay 22, 2024 · First, draw a sine wave with a 5 volt peak amplitude and a period of 25 s. Now, push the waveform down 3 volts so that the positive peak is only 2 volts and the negative peak is down at −8 volts. Finally, push the newly shifted waveform to the right by 5 s. The result is shown in Figure .

Websin α = side opposite hypotenuse and cos β = side adjacent hypotenuse. Notice that the side adjacent to β is the same as the side opposite of α, thus sin α = cos β. In addition, since this is a right triangle, α + β = π 2. So we can make a substitution for β = π 2 − α to say that sin α = cos ( π 2 − α) Share Cite Follow edited Apr 1, 2014 at 22:06 pete hardy neighboursWebM Abdul Rehman.
