sec(t)= 1/((sqrt(2))/2)

Solução

sec (t) = \frac{1}{\frac{2}{2}}

t = \frac{π}{4} + 2 πn, t = \frac{7 π}{4} + 2 πn

Passos da solução

sec (t) = \frac{1}{\frac{2}{2}}

Simplificar

\frac{1}{\frac{2}{2}} : 2

\frac{1}{\frac{2}{2}}

Aplicar as propriedades das frações:

\frac{1}{\frac{b}{c}} = \frac{c}{b}

= \frac{2}{2}

Aplicar as propriedades dos radicais:

n a = a^{\frac{1}{n}}

2 = 2^{\frac{1}{2}}

= \frac{2}{2 ^{\frac{1}{2}}}

Aplicar as propriedades dos expoentes:

\frac{x ^{a}}{x ^{b}} = x^{a - b}

\frac{2 ^{1}}{2 ^{\frac{1}{2}}} = 2^{1 - \frac{1}{2}}

= 2^{1 - \frac{1}{2}}

Subtrair:

1 - \frac{1}{2} = \frac{1}{2}

= 2^{\frac{1}{2}}

Aplicar as propriedades dos radicais:

a^{\frac{1}{n}} = n a

2^{\frac{1}{2}} = 2

= 2

- \frac{cos ( x ) - sin ( x )}{1 + sin ( 2 x )} = 0

2 cos (x) = cot (x)

tan (x) = \frac{60}{\frac{( - 20 - 90 )}{2}}

0.1 \cdot sin (θ) cos (53.1 3^{\circ}) + 0.1 \cdot sin (θ) = 0

tan (θ) = (1)
