The answer to whether sin(2x)-cot(x)=cot(x)cos(2x) is False

Popular >

prove sin(2x)-cot(x)=cot(x)cos(2x)

prove

sin (2 x) - cot (x) = cot (x) cos (2 x)

False

Solution steps

sin (2 x) - cot (x) = cot (x) cos (2 x)

Show that the two sides are not equal

For

sin (2 x) - cot (x) = cot (x) cos (2 x)

plug in

x = 1

sin (2 \cdot 1) - cot (1) = 0.26720 \dots

sin (2 \cdot 1) - cot (1)

Refine to a decimal form

= 0.26720 \dots

cot (1) cos (2 \cdot 1) = - 0.26720 \dots

cot (1) cos (2 \cdot 1)

Refine to a decimal form

= - 0.26720 \dots

The two sides are not equal

\Rightarrow False

tan (x) + cot (x) \cdot tan (x) = sec^{2} (x)

sin (4 θ) = \frac{3}{8} - cos (2 θ) + \frac{1}{8} cos (4 θ)

5 cos^{2} (x) - 2 cos (x) - 3 - sin^{2} (x) = 0

sin (x) cos (\frac{π}{6}) - cos (x) sin (\frac{π}{6}) = sin (x - \frac{π}{6})

cos^{4} (a) + 1 - sin^{4} (a) = 2 cos^{2} (a)
