prove 2tan(x)=(2sin(x))/(cos(x))

prove

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

True

Solution steps

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

Manipulating left side

2 tan (x)

Express with sin, cos

2 tan (x)

Use the basic trigonometric identity:

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

= 2 \cdot \frac{sin ( x )}{cos ( x )}

Simplify

2 \cdot \frac{sin ( x )}{cos ( x )} : \frac{2 sin ( x )}{cos ( x )}

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

Multiply fractions:

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

= \frac{sin ( x ) \cdot 2}{cos ( x )}

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

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

We showed that the two sides could take the same form

\Rightarrow True

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

sin (t) cos (t) = 1

\frac{1}{1 - sin ( B )} = sec^{2} (B) + sec (B) tan (B)

tan (6 0^{\circ}) = \frac{2 tan ( 3 0 ^{\circ} )}{1 - tan ^{2} ( 3 0 ^{\circ} )}

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