Question

Is cosx=0.61 find sin (x-pie over 2)

Answer 1

HI!!

Answer 2

mmm pie \(\pi\)

Answer 3

\[\sin(x-\frac{\pi}{2})=-\cos(x)\]

Answer 4

so put a minus sign in front of \(.61\)

Answer 5

No , it's if cos X is equal to 0.61 t6th en find sin and it gives me the X minus pie over 2

Answer 6

*then

Answer 7

yeah i got the question

Answer 8

if \[\cos(x)=.61\] then what is \[\sin(x-\frac{\pi}{2})\]

Answer 9

it is always true, no matter what \(x\) is, that \[\sin(x-\frac{\pi}{2})=-\cos(x)\]

Answer 10

so if \(\cos(x)=.61\) then \(\sin(x-\frac{\pi}{2})=-\cos(x)=-.61\)
