Find the exact value of each of the following. in each case, show your work and explain the steps you take to find the value. (1) sin 17pi/6 (2) tan 13pi/4 (3) sec 11pi/3

Step-by-step explanation:

Alright, lets get started.

You my refer the unit circle I have attached.

1)

We have to find exact value of this.

Usually, we could refer the unit circle and find the corresponding sin value of that angle but in this, angle is not on unit circle as it is more than 2.

So, first we will find co-terminal angle of by subtracting 2 from it.

So, its co-terminal angle is :

So, co-terminal angle will be =

So, referring unit circle,

   :   Answer

2)

Finding co-terminal :

So, referring unit circle,

   :   Answer

3)

Finding co-terminal:

Se we know, sec is reciprocal of cos, so we will flip the value of cos to find sec.

  :  Answer

it is a. 4.2 because 7.6-3.4 gets the remaining length of 4.2. i might be wrong but i am pretty sure this is the answer.
