3csc(A)-6=0

解答

3 csc (A) - 6 = 0

解答

A = \frac{π}{6} + 2 πn, A = \frac{5 π}{6} + 2 πn

+1

度数

A = 3 0^{\circ} + 36 0^{\circ} n, A = 15 0^{\circ} + 36 0^{\circ} n

求解步骤

3 csc (A) - 6 = 0

将

6

到右边

3 csc (A) - 6 = 0

两边加上

6

3 csc (A) - 6 + 6 = 0 + 6

化简

3 csc (A) = 6

3 csc (A) = 6

两边除以

3

3 csc (A) = 6

两边除以

3

\frac{3 csc ( A )}{3} = \frac{6}{3}

化简

csc (A) = 2

csc (A) = 2

csc (A) = 2

的通解

csc (x)

15cos^2(x)+sin(x)-9=0

15 cos^{2} (x) + sin (x) - 9 = 0

(tan(x)-1)/(1+tan(x))=0

\frac{tan ( x ) - 1}{1 + tan ( x )} = 0

arccos(x)+arccos(2x)= pi/2

arccos (x) + arccos (2 x) = \frac{π}{2}

sin^2(x)+sin(x)=cos^2(x)

sin^{2} (x) + sin (x) = cos^{2} (x)

-2-3sin(x)=1-6sin(x)

- 2 - 3 sin (x) = 1 - 6 sin (x)
