Sin5x + sin3x = 2sin4x.cosx
cos5x + cos3x = 2cos4x.cosx
so \frac{2sin4x.cosx}{2cos4x.cosx} = \frac{sin4x}{cos4x}
= tan4x

Phantasy [73]

Step-by-step explanation:

r = \sqrt{ \frac{ax - p}{q + bx} } \\  {r}^{2}  =  \frac{ax - p}{q + bx}

r² (q + bx) = ax - p

qr² + bxr² = ax - p

qr² + p = ax - bxr²

qr² + p = x (a - br²)

x =  \frac{q {r}^{2}  + p}{a - b {r}^{2} }
