simplify cos(x)(1-(cos(2x))/(y^2))

simplify

cos (x) (1 - \frac{cos ( 2 x )}{y ^{2}})

\frac{cos ( x ) ( y ^{2} - cos ( 2 x ) )}{y ^{2}}

Solution steps

cos (x) (1 - \frac{cos ( 2 x )}{y ^{2}})

Join

1 - \frac{cos ( 2 x )}{y ^{2}} : \frac{y ^{2} - cos ( 2 x )}{y ^{2}}

= cos (x) \frac{y ^{2} - cos ( 2 x )}{y ^{2}}

Apply the fraction rule:

a \cdot \frac{b}{c} = \frac{a \cdot b}{c}

= \frac{cos ( x ) ( y ^{2} - cos ( 2 x ) )}{y ^{2}}

\frac{1}{16} (e^{4 x} \cdot 4 x - e^{4 x})

\frac{2 ( 18 π + 16 ) 18 π + 16 - 128}{27}

\frac{( n + 1 ) ( 3 n + 7 )}{2}

\frac{a ^{2} + 8}{( a - 10 ) ( a + 10 )}
