sqrt(2)csc(θ)-2=0

2 csc (θ) - 2 = 0

θ = \frac{π}{4} + 2 πn, θ = \frac{3 π}{4} + 2 πn

Degrees

θ = 4 5^{\circ} + 36 0^{\circ} n, θ = 13 5^{\circ} + 36 0^{\circ} n

Solution steps

2 csc (θ) - 2 = 0

Move

2

to the right side

2 csc (θ) - 2 = 0

Add

2

to both sides

2 csc (θ) - 2 + 2 = 0 + 2

Simplify

2 csc (θ) = 2

2 csc (θ) = 2

Divide both sides by

2

2 csc (θ) = 2

Divide both sides by

2

\frac{2 csc ( θ )}{2} = \frac{2}{2}

Simplify

\frac{2 csc ( θ )}{2} = \frac{2}{2}

Simplify

\frac{2 csc ( θ )}{2} : csc (θ)

\frac{2 csc ( θ )}{2}

Cancel the common factor:

2

= csc (θ)

Simplify

\frac{2}{2} : 2

\frac{2}{2}

Apply radical rule:

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

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

Apply exponent rule:

\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}}

Subtract the numbers:

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

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

Apply radical rule:

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

= 2

csc (θ) = 2

csc (θ) = 2

csc (θ) = 2
