Answer:

  • A = 2
  • B = 3

Step-by-step explanation:

You can start by recognizing 19/12π = π +7/12π, so the desired sine is ...

  sin(19/12π) = -sin(7/12π) = -(sin(3/12π +4/12π)) = -sin(π/4 +π/3)

  -sin(π/4 +π/3) = -sin(π/4)cos(π/3) -cos(π/4)sin(π/3)

Of course, you know that ...

  sin(π/4) = cos(π/4) = (√2)/2

  cos(π/3) = 1/2

  sin(π/3) = (√3)/2

So, the desired value is ...

  sin(19π/12) = -(√2)/2×1/2 -(√2)/2×(√3/2) = -(√2)/4×(1 +√3)

Comparing this form to the desired answer form, we see ...

  A = 2

  B = 3

serg [7]

Answer:

Step-by-step explanation:

I think you are inventing symbols, which turns your question into a guessing game. You are better off describing the math symbols in words. Or post a picture.

I’m guessing that the math expression is ∛27 + √64² - 2 = 3 + 64 - 2 = 65

At how many points does the graph of the function below intersect the x<br> axis?<br> y= 16x2 - 8x+1
Radda [10]
Y= 16x2 - 8x+1 does not intersect the c axis. It only peaks at it. The parabola does not go over it.

Describe differences between recursive and explicit functions. Explain situations in which using a recursive or an explicit func
Misha Larkins [42]

Explanation:

An <em>explicit function</em> returns a value based only on the arguments given.

  y = f(x)

__

A <em>recursive function</em> returns a value based on the arguments given and on other values of the function.

  y = f(x, f(g(x))
