cos(x)=(sqrt(34))/(sqrt(70))

cos (x) = \frac{34}{70}

x = 0.79968 \dots + 2 πn, x = 2 π - 0.79968 \dots + 2 πn

Solution steps

cos (x) = \frac{34}{70}

Simplify

\frac{34}{70} : \frac{17}{35}

Apply trig inverse properties

x = arccos (\frac{17}{35}) + 2 πn, x = 2 π - arccos (\frac{17}{35}) + 2 πn

Show solutions in decimal form

x = 0.79968 \dots + 2 πn, x = 2 π - 0.79968 \dots + 2 πn

x, z = cos (x^{2} + 2 y)

- 3 sin (t) + 4 cos (t) = 0

cos (θ) = \frac{8}{6}

tan (x) = \frac{- 2 2}{2}

arctan (0.1 x) + arctan (0.01 x) = 3 9^{\circ}
