Popular >

prove (sin^2(x))/(sin(x))= 2/(sec(x))

prove

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

False

Solution steps

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

Show that the two sides are not equal

For

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

plug in

x = 1

\frac{sin ^{2} ( 1 )}{sin ( 1 )} = 0.84147 \dots

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

Refine to a decimal form

= 0.84147 \dots

\frac{2}{sec ( 1 )} = 1.08060 \dots

\frac{2}{sec ( 1 )}

Refine to a decimal form

= 1.08060 \dots

The two sides are not equal

\Rightarrow False

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

sin (3 x) = 3 sin (x) - 4 sin (3 x)

cos (2 b + b) = 4 cos^{3} (b) - 3 cos (b)

2 cos^{2} (A) = 1 + cos (2 A)

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