Question

$\frac{2 \tan(30) }{1 - \tan {2}^ (30) }$
​

Answer 1

Answer:

the polynomials x³ + ax² - 3x + 4 and ax³ - x² + 7 when divided by (x - 1) leave the remainder r and r respectively if r = 2r then find the value of a

Answer 2

Answer:

$\implies{\dfrac{2 \tan(30^\circ) }{1 - \tan {2}^ (30^\circ) }}$

$= tan(30^\circ + 30^\circ)$

$= tan(60^\circ)$

$= \sqrt3$
