Question

If 6x=90° then tan3x-tan2x-tanx=

Answer 1

$\tan(45) - \tan(30) - \tan(15) = 0.154700538$

Answer 2

Answer:

0.156

Step-by-step explanation:

It is given that $6x=90^{\circ}$

⇒$x={\frac{90^{\circ}}{6}}$

⇒$x=15^{\circ}$

Now, the value of $tan3x-tan2x-tanx$ will be:

$tan3x-tan2x-tanx=tan3(15^{\circ})-tan2(15^{\circ})-tan15^{\circ}$

=tan45^{\circ}-tan30^{\circ}-tan15^{\circ}[/tex]

=$1-0.577-0.267$

=$0.156$

Thus, the value fo the given equation will be 0.156.
