cos(x)=0.695

cos (x) = 0.695

x = 0.80237 \dots + 2 πn, x = 2 π - 0.80237 \dots + 2 πn

Solution steps

cos (x) = 0.695

Apply trig inverse properties

x = arccos (0.695) + 2 πn, x = 2 π - arccos (0.695) + 2 πn

Show solutions in decimal form

x = 0.80237 \dots + 2 πn, x = 2 π - 0.80237 \dots + 2 πn

3 + sec (x) = 5

cos (x) = \frac{3}{30}

- 5 sin (t) + 9 cos (t) = 0

sin (2.5 x) = 2.75 cos (2.5 x)

cos (x) + 1 - 2 sin^{2} (x) = 0
