sec(A)= 8/2

sec (A) = \frac{8}{2}

A = 1.31811 \dots + 2 πn, A = 2 π - 1.31811 \dots + 2 πn

Degrees

A = 75.52248 \dots^{\circ} + 36 0^{\circ} n, A = 284.47751 \dots^{\circ} + 36 0^{\circ} n

Solution steps

sec (A) = \frac{8}{2}

Divide the numbers:

\frac{8}{2} = 4

sec (A) = 4

Apply trig inverse properties

sec (A) = 4

General solutions for

sec (A) = 4

sec (x) = a \Rightarrow x = arcsec (a) + 2 πn, x = 2 π - arcsec (a) + 2 πn

A = arcsec (4) + 2 πn, A = 2 π - arcsec (4) + 2 πn

A = arcsec (4) + 2 πn, A = 2 π - arcsec (4) + 2 πn

Show solutions in decimal form

A = 1.31811 \dots + 2 πn, A = 2 π - 1.31811 \dots + 2 πn

sin (2 x) + sin (6 x) = 2 sin (4 x)

cos (x) = \frac{11}{2}

3 \frac{cos ^{2} ( a )}{sin ^{2} ( a )} = (cot (a))^{2}

cos (x) = \frac{- 2}{2}

tan (x) = - 0.22
