Question

Sketch the graph of the function cos 2x in the interval [0, π]

Answer 1

Answer:

Step-by-step explanation:

To sketch the trigonometric function cos 2x in the interval [0,π}

put different values of x in terms of angle

1) x=0°

cos 2(0°)=1

2) x= 30°

cos 2(30°)=>cos (60°)=1/2

3) x= 45°

cos 2(45°)=>cos (90°)=0

like that calculate few  values and plot

look at the attatchment.
