prove 6cos^2(A)-5=1-6sin^2(A)

prove

6 cos^{2} (A) - 5 = 1 - 6 sin^{2} (A)

True

Solution steps

6 cos^{2} (A) - 5 = 1 - 6 sin^{2} (A)

Manipulating left side

6 cos^{2} (A) - 5

Rewrite using trig identities

= - 6 sin^{2} (A) + 1

= 1 - 6 sin^{2} (A)

We showed that the two sides could take the same form

\Rightarrow True

sin (x) + \frac{cot ( x )}{sec ( x )} = csc (x)

\frac{sin ( 2 θ )}{sin ( θ )} = 2

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

- 2 sin (2 x + π) = - 2 sin (2 x - π)

cos (θ) (\frac{1}{1 - sin ( θ )}) = sec (θ) + tan (θ)
