Answer 3

I need wrte eqution ,period,amplitude,shift

Answer 4

just use a graphing software, like gsp, and see what it's like!

Answer 5

use caculator?

Answer 6

values for sinx (o,o) (pi/2,1) (pi,0) (3pi/2,-1) (2pi,0)
values for cosx (0,1)(pi/2,0) (pi,-1)(3pi2,0) (2pi,1)
now subtracts the corresponding y values you will get
y=sinx-cosx (0,-1) (pi/2,1) (pi,1)(3pi/2,-1) (2pi,-1)
you can see the patten that this function stays within max and min of 1 and -1 so amplitude is absolute value of that which is 1

Answer 7

how about period and vertical shift ?

Answer 9

how u get sinx=0?
