TRUE/FALSE. . Reflecting the graph of y=cos x across the y-axis is the same as reflecting it across the x-axis.
The statement,
reflecting the graph of y = cos x across the y-axis is the same as reflecting
it across the x-axis is FALSE. I am hoping that this answer has satisfied your
query and it will be able to help you, and if you would like, feel free to ask
another question.
Answer:
False.
Step-by-step explanation:
The reflecting graph across y-axis
Rules of reflection :
Along across y-axis if we have a point \((x,y)\rightarrow(-x,y)\)
Along across x-axis if we have a point \((x,y)\rightarrow(x,-y)\)
here, we have y= cos x
So, along x-axis it will become -y=cosx implies y= -cos x
And along y-axis it will become y=cos(-x)=cos x
Hence, both of them are not equal
Therefore, false.
