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

prove

sin (\frac{3 π}{4}) = \frac{2}{2}

True

Solution steps

sin (\frac{3 π}{4}) = \frac{2}{2}

Manipulating left side

sin (\frac{3 π}{4})

Simplify

= \frac{2}{2}

We showed that the two sides could take the same form

\Rightarrow True

tan (x) = cot (\frac{π}{2} - x)

\frac{tan ( x ) + 1}{sec ( x ) + csc ( x )} = sin (x)

sec (2 x) = \frac{csc ^{2} ( x )}{csc ^{2} ( x ) - 2}

\frac{1 - cos ( a )}{1 + cos ( a )} = tan^{2} (\frac{a}{2})

1 + \frac{cot ^{2} ( θ )}{csc ( θ ) + 1} = csc (θ)
