sec(θ/5)=sqrt(10)

sec (\frac{θ}{5}) = 10

θ = 5 \cdot 1.24904 \dots + 10 πn, θ = 10 π - 5 \cdot 1.24904 \dots + 10 πn

Solution steps

sec (\frac{θ}{5}) = 10

Apply trig inverse properties

\frac{θ}{5} = arcsec (10) + 2 πn, \frac{θ}{5} = 2 π - arcsec (10) + 2 πn

Solve

\frac{θ}{5} = arcsec (10) + 2 πn : θ = 5 arcsec (10) + 10 πn

Solve

\frac{θ}{5} = 2 π - arcsec (10) + 2 πn : θ = 10 π - 5 arcsec (10) + 10 πn

θ = 5 arcsec (10) + 10 πn, θ = 10 π - 5 arcsec (10) + 10 πn

Show solutions in decimal form

θ = 5 \cdot 1.24904 \dots + 10 πn, θ = 10 π - 5 \cdot 1.24904 \dots + 10 πn

(sin (x))^{4} = \frac{( cos ( x ) ) ^{2}}{2}

cos (θ) = \frac{15}{17}

3 sec^{2} (x) tan (x) = 4 tan (x)

csc^{2} (θ) = cot (θ) + 1

7 cos (x) tan (x) = - 8 tan (x)
