cos(a)= 1/(sqrt(3))

cos (a) = \frac{1}{3}

a = 0.95531 \dots + 2 πn, a = 2 π - 0.95531 \dots + 2 πn

Solution steps

cos (a) = \frac{1}{3}

Simplify

\frac{1}{3} : \frac{3}{3}

Apply trig inverse properties

a = arccos (\frac{3}{3}) + 2 πn, a = 2 π - arccos (\frac{3}{3}) + 2 πn

Show solutions in decimal form

a = 0.95531 \dots + 2 πn, a = 2 π - 0.95531 \dots + 2 πn

tan (θ) = - \frac{7}{4}

2 sin (x) tan (x) + 1 = tan (x) + 2 sin (x)

sec (y) = (\frac{5}{4})

\frac{sin ( 6 5 ^{\circ} )}{5} = \frac{sin ( x )}{4}

2 - 6.5 sin (x) = 0
