cos^2(A)+2=3cos(A)

Solution

cos^{2} (A) + 2 = 3 cos (A)

Solution

A = 2 πn

+1

Solution steps

cos^{2} (A) + 2 = 3 cos (A)

Solve by substitution

cos (A) = 2, cos (A) = 1

cos (A) = 2 :

No Solution

cos (A) = 1 : A = 2 πn

Combine all the solutions

A = 2 πn

sin (θ) = \frac{- 5}{6}

(sin(x))/(16)=(sin(31))/(12)

\frac{sin ( x )}{16} = \frac{sin ( 3 1 ^{\circ} )}{12}

sin (A) = \frac{2}{3}

3 cos (2 x + 1) = 2

sin(t)= 3/7 ,cos(t)

sin (t) = \frac{3}{7}, cos (t)
