prove tan(β)=(cos(β))/(sin(β)cot^2(β))

prove

tan (β) = \frac{cos ( β )}{sin ( β ) cot ^{2} ( β )}

True

Solution steps

tan (β) = \frac{cos ( β )}{sin ( β ) cot ^{2} ( β )}

Manipulating right side

\frac{cos ( β )}{sin ( β ) cot ^{2} ( β )}

Express with sin, cos

\frac{cos ( β )}{cot ^{2} ( β ) sin ( β )}

Use the basic trigonometric identity:

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

= \frac{cos ( β )}{( \frac{c o s ( β )}{s i n ( β )} ) ^{2} sin ( β )}

Simplify

\frac{cos ( β )}{( \frac{c o s ( β )}{s i n ( β )} ) ^{2} sin ( β )} : \frac{sin ( β )}{cos ( β )}

\frac{cos ( β )}{( \frac{c o s ( β )}{s i n ( β )} ) ^{2} sin ( β )}

(\frac{cos ( β )}{sin ( β )})^{2} = \frac{cos ^{2} ( β )}{sin ^{2} ( β )}

(\frac{cos ( β )}{sin ( β )})^{2}

Apply exponent rule:

(\frac{a}{b})^{c} = \frac{a ^{c}}{b ^{c}}

= \frac{cos ^{2} ( β )}{sin ^{2} ( β )}

= \frac{cos ( β )}{\frac{c o s ^{2} ( β )}{s i n ^{2} ( β )} sin ( β )}

Multiply

\frac{cos ^{2} ( β )}{sin ^{2} ( β )} sin (β) : \frac{cos ^{2} ( β )}{sin ( β )}

\frac{cos ^{2} ( β )}{sin ^{2} ( β )} sin (β)

Multiply fractions:

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

= \frac{cos ^{2} ( β ) sin ( β )}{sin ^{2} ( β )}

Cancel the common factor:

sin (β)

= \frac{cos ^{2} ( β )}{sin ( β )}

= \frac{cos ( β )}{\frac{c o s ^{2} ( β )}{s i n ( β )}}

Apply the fraction rule:

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

= \frac{cos ( β ) sin ( β )}{cos ^{2} ( β )}

Cancel the common factor:

cos (β)

= \frac{sin ( β )}{cos ( β )}

= \frac{sin ( β )}{cos ( β )}

= \frac{sin ( β )}{cos ( β )}

Use the basic trigonometric identity:

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

= tan (β)

We showed that the two sides could take the same form

\Rightarrow True

cos (2 θ) = cos^{(2)} (θ) - sin^{(2)} (θ)

2 sec (β) = 2 \cdot \frac{1}{cos ( β )}

\frac{sin ^{2} ( x )}{cos ( x )} = sin (x) tan (x)

csc^{2} (x) sec^{2} (x) = sec^{2} (x) + csc^{2} (x)

cot (s) = \frac{( sin ( 2 s ) )}{( 1 - cos ( 2 s ) )}
