Use the vertical line test to determine whether the relation is a function {(0,-1),(-5,1),(-3,-3),(-5,-5)}

Mathematics
1 answer:
AfilCa [17]3 years ago
5 0

Answer:

This relation is not a function

Step-by-step explanation:

Each x value has to have a different y value.  The second and 4th point have an x value of -5, but they have 2 different y-values, so that means there are 2 points here.  This fails the vertical line test, so this relation is not a function

Prove the following theorem indirectly. We will give you a start.. . Prove that a triangle cannot have two right angles.. A tria
ladessa [460]
<span>Suppose a triangle had two right angles.
The sum of all angles of any triangle is 180</span>°.
The measure of a right angle is 90°.
By difference, the measure of the other angle can be determined.
Since the two angles have a measure of 90° each, then by difference, the measure of the third angle is 180° - (90° + 90°) = 0°.
If the angle is 0°, there would only be two sides.
A triangle has three sides.
Therefore, a triangle can't have two right angles.

Sin(4x) in the term of just x<br> Please help!!
Nina [5.8K]

I think you mean in terms of \sin(x)?

Recall Euler's identity

e^{ix} = \cos(x) + i \sin(x)

and de Moivre's theorem

\left(e^{ix}\right)^n = \left(\cos(x) + i \sin(x)\right)^n = \cos(nx) + i \sin(nx) = e^{inx}

where i=\sqrt{-1}.

It follows that

\sin(4x) = \mathrm{Im}\left(\cos(x) + i \sin(x)\right)^4

By the binomial theorem, expanding the right side gives

\cos^4(x) + 4i \cos^3(x) \sin(x) - 6\cos^2(x) \sin^2(x) - 4i \cos(x) \sin^3(x) + \sin^4(x)

and so

\sin(4x) = 4\cos^3(x) \sin(x) - 4 \cos(x) \sin^3(x)

We can factorize this as

\sin(4x) = 4 \cos(x) \sin(x) \left(\cos^2(x) - \sin^2(x)\right)

and using the Pythagorean identity

\cos^2(x)+\sin^2(x) = 1 \implies \cos(x) = \pm \sqrt{1-\sin^2(x)}

this reduces to

\sin(4x) = \pm 4 \sqrt{1-\sin^2(x)} \sin(x) (1 - 2 \sin^2(x))
