cos(x)= 1249/1250

cos (x) = \frac{1249}{1250}

x = 0.04000 \dots + 2 πn, x = 2 π - 0.04000 \dots + 2 πn

Solution steps

cos (x) = \frac{1249}{1250}

Apply trig inverse properties

x = arccos (\frac{1249}{1250}) + 2 πn, x = 2 π - arccos (\frac{1249}{1250}) + 2 πn

Show solutions in decimal form

x = 0.04000 \dots + 2 πn, x = 2 π - 0.04000 \dots + 2 πn

sec (θ) = \frac{9}{7}

4 cos (x - π) = 4

cot (x) (tan (x) - \frac{3}{3}) = 0

3 = sec (x)

2 cos (2 x) = 1
