prove sin((3pi)/4)= 1/(sqrt(2))

prove

sin (\frac{3 π}{4}) = \frac{1}{2}

True

Solution steps

sin (\frac{3 π}{4}) = \frac{1}{2}

Manipulating left side

sin (\frac{3 π}{4})

Simplify

= \frac{2}{2}

= \frac{1}{2}

We showed that the two sides could take the same form

\Rightarrow True

sin (c) = 2 sin (\frac{c}{2}) cos (\frac{c}{2})

\frac{5 sin ( 2 θ )}{2 sin ( θ )} = 5 cos (θ)

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

\frac{tan ( a ) + cot ( a )}{tan ( a )} = csc^{2} (a)

sin (2 u) = 2 sin (u) cos (u)
