prove 1/(sin(x)cot(x))=sec(x)

prove

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

True

Solution steps

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

Manipulating left side

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

Express with sin, cos

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

Use the basic trigonometric identity:

cot (x) = \frac{cos ( x )}{sin ( x )}

= \frac{1}{\frac{c o s ( x )}{s i n ( x )} sin ( x )}

Simplify

\frac{1}{\frac{c o s ( x )}{s i n ( x )} sin ( x )} : \frac{1}{cos ( x )}

\frac{1}{\frac{c o s ( x )}{s i n ( x )} sin ( x )}

Multiply

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

\frac{cos ( x )}{sin ( x )} sin (x)

Multiply fractions:

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

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

Cancel the common factor:

sin (x)

= cos (x)

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

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

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

Rewrite using trig identities

Use the basic trigonometric identity:

cos (x) = \frac{1}{sec ( x )}

\frac{1}{\frac{1}{s e c ( x )}}

Simplify

\frac{1}{\frac{1}{s e c ( x )}}

Apply the fraction rule:

\frac{1}{\frac{b}{c}} = \frac{c}{b}

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

Apply rule

\frac{a}{1} = a

= sec (x)

sec (x)

sec (x)

We showed that the two sides could take the same form

\Rightarrow True

p ro v e csc (θ) + sin (θ) = \frac{2 - cos ^{2} ( θ )}{sin ( θ )}

p ro v e tan^{2} (x) - sin^{2} (x) = tan^{2} (x)

p ro v e sin (x) ((1 + cot^{2} (x))) = csc (x)

p ro v e \frac{1}{tan ^{2} ( x )} = \frac{cos ^{2} ( x )}{sin ^{2} ( x )}

p ro v e sin (3 θ) + sin (θ) = 2 sin (2 θ) cos (θ)
