simplify (cos^2(a)-cos^2(a))/(cos^2(cos^2(x)))

simplify

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

Solution steps

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

Apply Difference of Two Squares Formula:

x^{2} - y^{2} = (x + y) (x - y)

cos^{2} (a) - cos^{2} (a) = (cos (a) + cos (a)) (cos (a) - cos (a))

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

Simplify

\frac{( cos ( a ) + cos ( a ) ) ( cos ( a ) - cos ( a ) )}{cos ^{2} ( cos ^{2} ( x ) )} : \frac{0}{cos ^{2} ( cos ^{2} ( x ) )}

= \frac{0}{cos ^{2} ( cos ^{2} ( x ) )}

Apply rule

\frac{0}{a} = 0

a \neq = 0

= 0

\frac{( 16 x ^{3} - 6 x ^{2} + 12 x + 4 )}{2}

(1 - a)^{4}

cos (9 0^{\circ}) - x

5 x - [\frac{20}{25} + \frac{14}{28} + \frac{17.5}{35} + 2] x

x^{1} - x^{1} - 2 x
