2sec(x)+2=6

2 sec (x) + 2 = 6

x = \frac{π}{3} + 2 πn, x = \frac{5 π}{3} + 2 πn

Degrees

x = 6 0^{\circ} + 36 0^{\circ} n, x = 30 0^{\circ} + 36 0^{\circ} n

Solution steps

2 sec (x) + 2 = 6

Move

2

to the right side

2 sec (x) + 2 = 6

Subtract

2

from both sides

2 sec (x) + 2 - 2 = 6 - 2

Simplify

2 sec (x) = 4

2 sec (x) = 4

Divide both sides by

2

2 sec (x) = 4

Divide both sides by

2

\frac{2 sec ( x )}{2} = \frac{4}{2}

Simplify

sec (x) = 2

sec (x) = 2

x = \frac{π}{3} + 2 πn, x = \frac{5 π}{3} + 2 πn

arctan (\frac{1}{x}) = arctan (- x)

14928 = \frac{18177}{( 1 + 0.387 cos ( x ) )}

sin^{2} (θ) - 3 cos (θ) = 4

sec^{2} (x) - 2 = 0, 0 \leq x \leq 2 π

cos^{2} (x) - 2 sin (x) = 1
