prove (sin(x))/(1+cos(2x))=tan(x)

prove

\frac{sin ( x )}{1 + cos ( 2 x )} = tan (x)

False

Solution steps

\frac{sin ( x )}{1 + cos ( 2 x )} = tan (x)

Show that the two sides are not equal

For

\frac{sin ( x )}{1 + cos ( 2 x )} = tan (x)

plug in

x = 1

\frac{sin ( 1 )}{1 + cos ( 2 \cdot 1 )} = 1.44123 \dots

\frac{sin ( 1 )}{1 + cos ( 2 \cdot 1 )}

Refine to a decimal form

= 1.44123 \dots

tan (1) = 1.55740 \dots

tan (1)

Refine to a decimal form

= 1.55740 \dots

The two sides are not equal

\Rightarrow False

cos^{2} (\frac{( 12 π )}{2}) = cos^{2} (12 π)

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

sec (t) (csc (t) (tan (t) + cot (t))) = sec^{2} (t) + csc^{2} (t)

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

2 sin^{2} (x) + sin (x) = 0
