prove sin((5pi)/6)= 1/2

prove

sin (\frac{5 π}{6}) = \frac{1}{2}

True

Solution steps

sin (\frac{5 π}{6}) = \frac{1}{2}

Manipulating left side

sin (\frac{5 π}{6})

Simplify

= \frac{1}{2}

We showed that the two sides could take the same form

\Rightarrow True

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

tan (\frac{π}{2} - θ) = cot (θ)

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

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

sec (2 a) = \frac{csc ^{2} ( a )}{cot ^{2} ( a ) - 1}
