The cosine function is positive in the first and fourth quadrants. To find the second solution, subtract the ... Graph y=cos(x)-1. Step 1. Use the form to find the variables used to find the amplitude, period, phase shift, and vertical shift. Step 2. Find the amplitude . Amplitude:We would like to show you a description here but the site won’t allow us.It follows that. arccos(cos x) = arccos(cos(d(x))) = d(x) (x ∈ R) , arccos ( cos x) = arccos ( cos ( d ( x))) = d ( x) ( x ∈ R) , which reveals arccos ∘ cos arccos ∘ cos to be a sawtooth function.
