What are the sine, cosine, and tangent of Θ = 3 pi over 4 radians?
Daniel [21]
Our angle teta is:
teta = 3pi/4

since that is larger than pi/2 but less than pi that means that our angle lies in II quadrant (x negative y positive)

sin(3pi/4) = √2/2
cosine and tangent of that angle must be negative because of position of the angle.

cos(3pi/4) = -√2/2
tan(3pi/4) = -1

The graph of a quadratic function intercepts the x-axis in two places and the y-axis in one place.
solmaris [256]

The true statement about the quadratic function is that it has two distinct real zeros

<h3>How to interpret the quadratic function?</h3>

The given parameters are:

  • x-intercepts = 2 i.e. intercepts the x-axis in two places
  • y-intercept = 1 i.e. intercepts the y-axis in one place

The first highlight above means that, the function can be represented as:

y = a(x - x1)(x -x2)

Where x1 and x2 are the x-intercepts

This also means that the quadratic function has two distinct real zeros
