cos(x)= 6/14

cos (x) = \frac{6}{14}

x = 1.12788 \dots + 2 πn, x = 2 π - 1.12788 \dots + 2 πn

Solution steps

cos (x) = \frac{6}{14}

Cancel the common factor:

2

cos (x) = \frac{3}{7}

Apply trig inverse properties

x = arccos (\frac{3}{7}) + 2 πn, x = 2 π - arccos (\frac{3}{7}) + 2 πn

Show solutions in decimal form

x = 1.12788 \dots + 2 πn, x = 2 π - 1.12788 \dots + 2 πn

x, sec (x) = 2

sin (θ) = sin (- \frac{2}{3} π)

cot (a) = - \frac{7}{24}

2 sin^{2} (a) = - sin (a)

sec (θ) = 5
