csc(x)+cot(x)=1,0<= x<= 2pi

Solution

csc (x) + cot (x) = 1, 0 \leq x \leq 2 π

Solution

x = \frac{π}{2}

Degrees

x = 9 0^{\circ}

Solution steps

csc (x) + cot (x) = 1, 0 \leq x \leq 2 π

Subtract

1

from both sides

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

Express with sin, cos

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

Simplify

\frac{1}{sin ( x )} + \frac{cos ( x )}{sin ( x )} - 1 : \frac{1 + cos ( x ) - sin ( x )}{sin ( x )}

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

Combine the fractions

\frac{1}{sin ( x )} + \frac{cos ( x )}{sin ( x )} : \frac{1 + cos ( x )}{sin ( x )}

Apply rule

\frac{a}{c} \pm \frac{b}{c} = \frac{a \pm b}{c}

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

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

Convert element to fraction:

1 = \frac{1 sin ( x )}{sin ( x )}

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

Since the denominators are equal, combine the fractions:

\frac{a}{c} \pm \frac{b}{c} = \frac{a \pm b}{c}

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

Multiply:

1 \cdot sin (x) = sin (x)

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

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

\frac{f ( x )}{g ( x )} = 0 \Rightarrow f (x) = 0

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

Add

sin (x)

to both sides

1 + cos (x) = sin (x)

Square both sides

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

Subtract

sin^{2} (x)

from both sides

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

Factor

(1 + cos (x))^{2} - sin^{2} (x) : (1 + cos (x) + sin (x)) (1 + cos (x) - sin (x))

(1 + cos (x))^{2} - sin^{2} (x)

Apply Difference of Two Squares Formula:

x^{2} - y^{2} = (x + y) (x - y)

(1 + cos (x))^{2} - sin^{2} (x) = ((1 + cos (x)) + sin (x)) ((1 + cos (x)) - sin (x))

= ((1 + cos (x)) + sin (x)) ((1 + cos (x)) - sin (x))

Refine

= (cos (x) + sin (x) + 1) (cos (x) - sin (x) + 1)

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

Solving each part separately

1 + cos (x) + sin (x) = 0 or 1 + cos (x) - sin (x) = 0

1 + cos (x) + sin (x) = 0, 0 \leq x \leq 2 π : x = π, x = \frac{3 π}{2}

1 + cos (x) + sin (x) = 0, 0 \leq x \leq 2 π

Rewrite using trig identities

1 + cos (x) + sin (x)

sin (x) + cos (x) = 2 sin (x + \frac{π}{4})

sin (x) + cos (x)

Rewrite as

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

Use the following trivial identity:

cos (\frac{π}{4}) = \frac{1}{2}

Use the following trivial identity:

sin (\frac{π}{4}) = \frac{1}{2}

= 2 (cos (\frac{π}{4}) sin (x) + sin (\frac{π}{4}) cos (x))

Use the Angle Sum identity:

sin (s + t) = sin (s) cos (t) + cos (s) sin (t)

= 2 sin (x + \frac{π}{4})

= 1 + 2 sin (x + \frac{π}{4})

1 + 2 sin (x + \frac{π}{4}) = 0

Move

1

to the right side

1 + 2 sin (x + \frac{π}{4}) = 0

Subtract

1

from both sides

1 + 2 sin (x + \frac{π}{4}) - 1 = 0 - 1

Simplify

2 sin (x + \frac{π}{4}) = - 1

2 sin (x + \frac{π}{4}) = - 1

Divide both sides by

2

2 sin (x + \frac{π}{4}) = - 1

Divide both sides by

2

Undefined

\Rightarrow False

Check the solution

\frac{3 π}{2} :

False

\frac{3 π}{2}

Plug in

n = 1

\frac{3 π}{2}

For

csc (x) + cot (x) = 1

plug in

x = \frac{3 π}{2}

csc (\frac{3 π}{2}) + cot (\frac{3 π}{2}) = 1

Refine

- 1 = 1

\Rightarrow False

Check the solution

\frac{π}{2} :

True

\frac{π}{2}

Plug in

n = 1

\frac{π}{2}

For

csc (x) + cot (x) = 1

plug in

x = \frac{π}{2}

csc (\frac{π}{2}) + cot (\frac{π}{2}) = 1

Refine

1 = 1

\Rightarrow True

x = \frac{π}{2}
