0.34=cos(x)

0.34 = cos (x)

x = 1.22387 \dots + 2 πn, x = 2 π - 1.22387 \dots + 2 πn

Solution steps

0.34 = cos (x)

Switch sides

cos (x) = 0.34

Apply trig inverse properties

x = arccos (0.34) + 2 πn, x = 2 π - arccos (0.34) + 2 πn

Show solutions in decimal form

x = 1.22387 \dots + 2 πn, x = 2 π - 1.22387 \dots + 2 πn

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

(tan (x) - 1) (cos (x) - 1) = 0

sin (y) = \frac{4}{12}

x, 2 y sin (x) = 0

2 sin^{2} (\frac{θ}{2}) - 2 cos^{2} (θ) = 0
