受欢迎的三角函数 >

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

解答

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

解答

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

求解步骤

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

化简

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

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

使用分式法则:

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

= \frac{2}{2}

使用根式运算法则:

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

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

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

使用指数法则:

\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}}

数字相减:

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

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

使用根式运算法则:

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

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

= 2

sec (t) = 2

-(cos(x)-sin(x))/(1+sin(2x))=0

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

sqrt(2)cos(x)=cot(x)

2 cos (x) = cot (x)

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

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

0.1*sin(θ)cos(53.13)+0.1*sin(θ)=0

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

tan (θ) = (1)
