cos(x)= 9/17

cos (x) = \frac{9}{17}

x = 1.01288 \dots + 2 πn, x = 2 π - 1.01288 \dots + 2 πn

Solution steps

cos (x) = \frac{9}{17}

Apply trig inverse properties

x = arccos (\frac{9}{17}) + 2 πn, x = 2 π - arccos (\frac{9}{17}) + 2 πn

Show solutions in decimal form

x = 1.01288 \dots + 2 πn, x = 2 π - 1.01288 \dots + 2 πn

- 6 sin (c) + 0 = sin (c) - 3

tan (x) = \frac{11}{12}

2 cos (a) + 3 = 4

tan (x) cot (x) - 3 tan (x) = 0

cos (θ) = 0.139
