5sec(x)=2sec(x)+7

5 sec (x) = 2 sec (x) + 7

x = 1.12788 \dots + 2 πn, x = 2 π - 1.12788 \dots + 2 πn

Solution steps

5 sec (x) = 2 sec (x) + 7

Solve by substitution

sec (x) = \frac{7}{3}

sec (x) = \frac{7}{3} : x = arcsec (\frac{7}{3}) + 2 πn, x = 2 π - arcsec (\frac{7}{3}) + 2 πn

Combine all the solutions

x = arcsec (\frac{7}{3}) + 2 πn, x = 2 π - arcsec (\frac{7}{3}) + 2 πn

Show solutions in decimal form

x = 1.12788 \dots + 2 πn, x = 2 π - 1.12788 \dots + 2 πn

sin (x) = (\frac{5}{9})

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

cos (θ) = \frac{198.36}{229.4}

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

- cos (2 x + 3) = 0
