Find \tan\left(\frac{17\pi}{12}\right)tan( 12 17π )tangent, left parenthesis, start fraction, 17, pi, divided by, 12, end frac

uranmaximum [27]

One way to do this is to notice

$\dfrac{17\pi}{12}=\dfrac\pi6+\dfrac{5\pi}4$

Then

$\tan\dfrac{17\pi}{12}=\tan\left(\dfrac\pi6+\dfrac{5\pi}4\right)=\dfrac{\tan\frac\pi6+\tan\frac{5\pi}4}{1-\tan\frac\pi6\tan\frac{5\pi}4}$

We have

$\tan\dfrac\pi6=\dfrac{\sin\frac\pi6}{\cos\frac\pi6}=\dfrac{\frac12}{\frac{\sqrt3}2}=\dfrac1{\sqrt3}$

and since $\tan x$ has a period of $\pi$ ,

$\tan\dfrac{5\pi}4=\tan\left(\pi+\dfrac\pi4\right)=\tan\dfrac\pi4=1$

and so

$\tan\dfrac{17\pi}{12}=\dfrac{\frac1{\sqrt3}+1}{1-\frac1{\sqrt3}}=\dfrac{1+\sqrt3}{\sqrt3-1}=2+\sqrt3$

How do you find the length of both legs of a right triangle with only the hypotenuse

Lina20 [59]

If you had the hypotenuse and one of the legs you could subtract the to using Pythagorean theorem. you cant answer the question unless you have another leg or a degree or a right triangle. <span />

Aaron is reading a graph of equivalent ratios. If one of the ratios is represented as (6, 2), which could be another ratio?

evablogger [386]

There Are Unlimited Equivalent Ratios To This! For One, We Could Simplify This Ratio To 3,1.Another One Would Be 12,4. You See, It Can Be Any Ratio As Long As It Equals(Simplified) To 3/1. I Hope This Helps!
