prove sqrt(81-9(3sin(x))^2)=csc^2(x)

prove

81 - 9 (3 sin (x))^{2} = csc^{2} (x)

False

Solution steps

81 - 9 (3 sin (x))^{2} = csc^{2} (x)

Show that the two sides are not equal

For

81 - 9 (3 sin (x))^{2} = csc^{2} (x)

plug in

x = 1

81 - 9 (3 sin (1))^{2} = 4.86272 \dots

81 - 9 (3 sin (1))^{2}

Refine to a decimal form

= 4.86272 \dots

csc^{2} (1) = 1.41228 \dots

csc^{2} (1)

Refine to a decimal form

= 1.41228 \dots

The two sides are not equal

\Rightarrow False

cos^{4} (β) - sin^{4} (β) = cos (2 β)

\frac{cot ( θ ) - 1}{1 - tan ( θ )} = cot (θ)

cot (x) = \frac{1 + cot ( x )}{1 + tan ( x )}

\frac{1}{- sin ( x )} + sin (x) = - cos (x) cot (x)

6 cos^{2} (B) - 6 sin^{2} (B) = 12 cos^{2} (B) - 6
