Hello,
Since 3sin x-4sin^3x=sin (3x) (*****)
3sin x-4sin^3x=-1
==>sin (3x)=-1
==>3x=3π/2 +2kπ
==>x=π/2+2kπ/3, k being an integer
(*****)
sin (3x)=sin(x+2x)=sin x cos2x+cos x sin 2x
=sin x(cos²x-sin²x)+2cos²x sin x
=sin x(cos²x+2cos²x-sin²x)
=sinx(3(1-sin²x)-sin²x)
=3sin x-4sin^3x
Answer:
<em>1:45 P.M</em>
Step-by-step explanation:
time = 60 + 45 + 60 + 40 + 60 + 5 = 180 + 90 = 270
270/60 = 4 hrs and 30 mins
6:15 - 4 hrs = 2:15
2:15 - 30 mins = 1:45 pm
Sorry but I can’t see the pic,it’s blurry!
Let's begin by listing out the information given to us:
