simplify (cos^2(a)-a)/(2-1)

simplify

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

cos^{2} (a) - a

Solution steps

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

Subtract the numbers:

2 - 1 = 1

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

Apply the fraction rule:

\frac{a}{1} = a

= cos^{2} (a) - a

3 a^{2} \cdot (5 a)^{- 2}

\frac{( 4 r ^{6} + 3 r ^{4} - 2 r ^{2} )}{2 r}

c^{1} v + c^{2}

\frac{ln ( e )}{x ^{2}}

12 c^{1} (0.003)^{1} (0.997)^{12} - 1
