受欢迎的三角函数 >

b= 3/((cot(x)))

解答

b = \frac{3}{( cot ( x ) )}

解答

x = arccot (\frac{3}{b}) + πn

求解步骤

b = \frac{3}{( cot ( x ) )}

交换两边

\frac{3}{cot ( x )} = b

在两边乘以

cot (x)

\frac{3}{cot ( x )} = b

在两边乘以

cot (x)

\frac{3}{cot ( x )} cot (x) = b cot (x)

化简

3 = b cot (x)

3 = b cot (x)

交换两边

b cot (x) = 3

两边除以

b; b \neq = 0

b cot (x) = 3

两边除以

b; b \neq = 0

\frac{b cot ( x )}{b} = \frac{3}{b}; b \neq = 0

化简

cot (x) = \frac{3}{b}; b \neq = 0

cot (x) = \frac{3}{b}; b \neq = 0

使用反三角函数性质

cot (x) = \frac{3}{b}

cot (x) = \frac{3}{b}

的通解

cot (x) = a \Rightarrow x = arccot (a) + πn

x = arccot (\frac{3}{b}) + πn

x = arccot (\frac{3}{b}) + πn
