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

prove

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

False

Solution steps

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

Show that the two sides are not equal

For

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

plug in

x = 1

\frac{sin ^{2} ( 1 )}{cos ^{2} ( 1 )} = 2.42551 \dots

\frac{sin ^{2} ( 1 )}{cos ^{2} ( 1 )}

Refine to a decimal form

= 2.42551 \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) tan (x) = sec (x) (1 - cos^{2} (x))

4 \cdot sin (\frac{x}{4}) \cdot cos (\frac{x}{4}) cos (\frac{x}{2}) = sin (x)

\frac{sin ( x )}{cos ( x ) + sin ( x )} = 11

sin (4 x) = sin (2 (2 x))

\frac{1 + cos ( a )}{sin ( a )} = cot (\frac{a}{s})
