cot(x)-cot(x)csc(x)=0

cot (x) - cot (x) csc (x) = 0

x = \frac{π}{2} + πn

Degrees

x = 9 0^{\circ} + 18 0^{\circ} n

Solution steps

cot (x) - cot (x) csc (x) = 0

Factor

cot (x) - cot (x) csc (x) : - cot (x) (csc (x) - 1)

cot (x) - cot (x) csc (x)

Factor out common term

- cot (x)

= - cot (x) (- 1 + csc (x))

- cot (x) (csc (x) - 1) = 0

Solving each part separately

cot (x) = 0 or csc (x) - 1 = 0

cot (x) = 0 : x = \frac{π}{2} + πn

cot (x) = 0

General solutions for

cot (x) = 0

x = \frac{π}{2} + πn

x = \frac{π}{2} + πn

csc (x) - 1 = 0 : x = \frac{π}{2} + 2 πn

csc (x) - 1 = 0

Move

1

to the right side

csc (x) - 1 = 0

Add

1

to both sides

csc (x) - 1 + 1 = 0 + 1

Simplify

csc (x) = 1

csc (x) = 1
