cos(x)= 7/8

cos (x) = \frac{7}{8}

x = 0.50536 \dots + 2 πn, x = 2 π - 0.50536 \dots + 2 πn

Solution steps

cos (x) = \frac{7}{8}

Apply trig inverse properties

x = arccos (\frac{7}{8}) + 2 πn, x = 2 π - arccos (\frac{7}{8}) + 2 πn

Show solutions in decimal form

x = 0.50536 \dots + 2 πn, x = 2 π - 0.50536 \dots + 2 πn

cos (6 x) = 1, 0 \leq x \leq \frac{π}{2}

cos^{2} (θ) + 2 cos (θ) - 3 = 0

3 + 6 sin (3 t) = 0

cos (2 θ) = 11 sin (θ) - 5

- sin (2 x) sin (x) + cos (x) = 0
