Answer:

1.-    

a)      θ =  45 ° + 360k

         θ =  135° + 360k

b)        θ =  45 °             0 ≤  θ < 360°

          θ =  135°  

2.-    

a)          θ  =  30° + 360k

            θ  = 330° + 360k

b)         θ  =  30°      0  ≤  θ  < 360°

           θ  = 330°

3.-        

a)         θ    =  60°  + 360k

            θ   =   240° + 360k

b)         θ    =  60°           0  ≤   θ < 360°

            θ    = 240°  

Step-by-step explanation:

1)    2 sin θ  = √2

   sin θ   =  √2/2

1.a )   θ =  45 ° + 360k

         θ =  135° + 360k

1.b)     θ =  45 °             0 ≤  θ < 360°

          θ =  135°  

2.

2  cos  θ  -  √3   =  0

2  cos  θ  = √3  

    cos  θ  = √3/2

2.a        θ  =  30° + 360k

            θ  = 330° + 360k

2.b     θ  =  30°      0  ≤  θ  < 360°

           θ  = 330°

3.-     √3 cot  θ  -  1  = 0

         √3 cot  θ    =  1

              cot  θ    =  1 /√3

3.a          θ    =  60°  + 360k

               θ   =   240° + 360k

3.b           θ    =  60°           0  ≤   θ < 360°

                θ    = 240°

<h3>Answer:  C)  -1/2</h3>

=============================================

Explanation:

We'll apply the derivative to get

g(x) = 4x^3 + 3x^2

g ' (x) = 3*4x^2 + 2*3x

g ' (x) = 12x^2 + 6x

Set that equal to 0 and solve for x. We do this to find where the horizontal tangents are located.

g ' (x) = 0

12x^2 + 6x = 0

6x(2x + 1) = 0

6x = 0 or 2x+1 = 0

x = 0 or x = -1/2

Adding those two said solutions yields us the final answer choice C
