The graph of the equation given by y=-cosu00b3u03b8 will be as follows:
Answer with explanation:
The given cosine function is
y= – cos 3 (theta)= -3 cos A, where , theta =A.
u2192u2192Domain of Cos A
= All Real number
= Period is from (-u03c0 , u03c0)
Range of Cos A=[-1, 1]
u2192Domain of Cos 3 A,will be also, all real number.
Period is from,
[tex][frac{-pi}{3},frac{pi}{3}][/tex]
But range of Cos 3A,will be same as ,Cos A which is equal to ,[-1,1].
u2192Plotted the graph of ,y=-cos 3 A, having cycle ,
