find the value of tan 1/2θ when tanθ is 3/4

Question

anonymous · Answer

so the first step is to take the inverse tan of 3/4; this will give u the angle u need. Then sub that answer into 1/(2*phi) and solve.

Give it a try

@Nutty First of all you have to find the value of θ

You are given that,

$$\tanθ =3/4$$

We have to find,

$$\tan \frac{ 1 }{ 2\theta }=?$$


I would suggest yoiu to start out with finding θ.

@Nutty I hope it is clear ?

im guessing the question is asking for $$\tan (\frac{ 1 }{ 2 }\theta)$$
so he'll need to use half angle formulae for sin and cos.
and from tan(theta) = 3/4 you should be able to tell what sin(theta) and cos(theta) are.

use the formula :
