Use the form acos(bx−c)+ d a cos (b x - c) + d to find the variables used to find the amplitude, period, phase shift, and vertical shift. Find the amplitude |a| | a |. Find the period of cos(4x) cos (4 x). Tap for more steps... Find the phase shift using the formula c b c b. Tap for more steps... List the properties of the trigonometric function.

By using the cosine addition formula, the cosine of both the sum and difference of two angles can be found with the two angles' sines and cosines. Hence, the formula cos 4 x = 8 cos 4 x − 8 cos 2 x + 1.

How do you find the domain and range of \displaystyle- {3} {\cos { {x}}} ? Domain = \displaystyle\mathbb {R} . Rangge = \displaystyle {\left [- {3}, {3}\right]} Explanation: Any general cosine graph of the form \displaystyle {y}= {A} {\sin { {B}}} {x} has amplitude of \displaystyle {A} ...

You probably mean using $\cos^2x=(1+\cos2x)/2$, so $$ \cos^4x=\frac{1}{4}(1+2\cos2x+\cos^22x) $$ Now apply the same to $\cos^22x$.

What is the general solution for cos(4x)=0 ? The general solution for cos(4x)=0 is x= pi/8+(pin)/2 ,x=(3pi)/8+(pin)/2

\cos{x} is a function. It takes an angle as its input and gives a real number between -1 \text{ and } 1 as output. When you dealing with real numbers, be assured that every time, x\times -x = -x^2 ...
