9.2cos(x)=6.3

9.2 cos (x) = 6.3

x = 0.81649 \dots + 2 πn, x = 2 π - 0.81649 \dots + 2 πn

Solution steps

9.2 cos (x) = 6.3

Multiply both sides by

10

92 cos (x) = 63

Divide both sides by

92

cos (x) = \frac{63}{92}

Apply trig inverse properties

x = arccos (\frac{63}{92}) + 2 πn, x = 2 π - arccos (\frac{63}{92}) + 2 πn

Show solutions in decimal form

x = 0.81649 \dots + 2 πn, x = 2 π - 0.81649 \dots + 2 πn

sec (x) + 3 tan (x) = 1 + 2 tan (x)

2 sin (3 x) = 0

x, cos (x) - sin (x + y) = 0

sin (x) = - cos (4 x)

cos (θ) = \frac{2}{3 38}
