Question

Demostrar:

(1 – Cos2x)(1 + Tan2x) = Tan2x

Answer 1

Explicación paso a paso:

$(1 - \cos \times 2x)(1 + \tan \times 2x) = \tan \times 2x$

$(1 - 0.999390827x)(1 + 0.03492076949x) = 0.03492076949x$

$+ (6.01729809x) + ( + 1 + 0.03492076949x) = 0.03492076949x$

$6.01729809x + 1 + 0.03492076949x = 0.03492076949x$

$- 0.03492076949x+ 6.01729809x +0.03492076949x = - 1$

$6.01729809x = - 1$

$x = - \frac{ 1}{6.01729809}$

$x = - 0.1661875455$
