Question

Solve the given equation. (Enter your answers as a comma-separated list. Let k be any integer. Round terms to three decimal places where appropriate. If there is no solution, enter NO SOLUTION.)

2 cos^2(θ) − sin(θ) = 1

θ = (List of numbers rounded to three decimal place)

I need help finding the list of numbers that are rounded to three decimal places?

I don't know how to figure out how many list of numbers I need to put?

Answer 1

a los²o-sino = ΟΥ Roll using 2(1-Sinha) - Sino=1 sin²o+ cos²0=1 2-asinto - sino = 1 costo=f-sinto -25o-sino +1 -0 asinto + sino-1=0 a sin²o + q sino - Sind-1=0 2 Sino (sino +1) -1 (sino+1)=0 ( Taking common } (Sino +1) (asino-1) = asino-1=0 Sin oth =0 a Sina=1 Sino =-1 Sino=1 - sint (1) = 3ū Şzinc, Sin (t) = sin (1-1)} 2 Since sino is periodic =) Sino = 1/3 and Sintr-o = 1 / So add period 2km, 0= Sin" (1) 17-0= Sin"(U) 3T + Q1IT, KEZ -oT 2 O= SIT o=I+QIT SI +2 ICTT 6.
