prove 4sin^2(x)tan(x)=tan(x)

prove

4 sin^{2} (x) tan (x) = tan (x)

False

Solution steps

4 sin^{2} (x) tan (x) = tan (x)

Show that the two sides are not equal

For

4 sin^{2} (x) tan (x) = tan (x)

plug in

x = 1

4 sin^{2} (1) tan (1) = 4.41103 \dots

4 sin^{2} (1) tan (1)

Refine to a decimal form

= 4.41103 \dots

tan (1) = 1.55740 \dots

tan (1)

Refine to a decimal form

= 1.55740 \dots

The two sides are not equal

\Rightarrow False

sin (x) = \frac{3}{4} \cdot \frac{sin ( x )}{\frac{3}{4}}

(tan (x) + 2) = 2 + sec (x) sin (x)

tan (θ - 4 5^{\circ}) + tan (θ + 4 5^{\circ}) = 2 tan (2 θ)

tan (2 θ) - tan (θ) = tan (θ) sec (2 θ)

\frac{sin ( x )}{csc ( x )} = sin^{2} (x)
