simplify cos^2(x)(2+tan^2(x))-1

simplify

cos^{2} (x) (2 + tan^{2} (x)) - 1

cos^{2} (x)

Solution steps

cos^{2} (x) (2 + tan^{2} (x)) - 1

Expand

cos^{2} (x) (2 + tan^{2} (x)) : - sin^{2} (x) + 2

= - sin^{2} (x) + 2 - 1

Subtract the numbers:

2 - 1 = 1

= - sin^{2} (x) + 1

Rewrite using trig identities

= cos^{2} (x)

(e^{z}) \circ (z^{4} + i z^{2} + (3 - i))

\frac{2 ( 33 - 417 )}{3}

\frac{x ^{5} + 34.5 x ^{4} + 64 x ^{3} + 54}{x ^{4} ( x - 1.5 ) ^{2}}

\frac{( a - b )}{a b - b a}

\frac{x ^{2}}{( 8 + x ) ^{3}}
