Question

the graph of y=-cos x is a reflection of the y=sin(x+pi/2) on the x-axis.

Answer 1

is this true of false.??

Answer 2

Is this a true false question?

You need to graph each of these curves . First start with the -cos(x), what does that look like?

Answer 3

yes

Answer 4

Sorry , I don't get images on my phone.
But! It should start at -1 on the y axis and start going up.

Now the other graph has a phase shift, do you remember how to put the equation in a form to show phase shift?

Answer 5

The +pi/2 means you slide the normal sin x curve to the LEFT pi/2 on the graph
