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

simplify

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

sec (x)

Solution steps

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

Express with sin, cos

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

Rewrite using trig identities

= sec (x)

x^{4} - 1 x^{3} - 11 x^{2} + x - 11

3^{27} x^{6}

(1 + r)^{25}

(\frac{( 49 a ^{- 8} )}{( 25 b ^{6} )})^{\frac{21}{2}}

11 + p (n - m) + 11 + p (m - n)
