\frac{1}{2} (1 - cos (θ)) : \frac{1 - cos ( θ )}{2}

= \frac{1 - cos ( θ )}{2}

e x p an d 125 e^{(l n (\frac{37}{125}) - 4) (\frac{1}{3})}

e x p an d - e^{x} (x + 1)

e x p an d \frac{4}{( 4 x - 3 ) ( 4 n + 1 )}

e x p an d \frac{z ( z - 3 )}{z ^{2} - 6 z + 8}

e x p an d \frac{( 1 + 2 x ) ^{\frac{1}{2}}}{( 1 + x ) ^{3}}
