Cos 4θ − cos 2θ = sin θ
hichkok12 [17]
cos(4\theta) - cos(2\theta) = sin(\theta)
-2sin(\frac{4\theta + 2\theta}{2})sin(\frac{4\theta - 2\theta}{2}) = sin(\theta)
-2sin(\frac{6\theta}{2}sin\frac{2\theta}{2}) = sin(\theta)
-2sin(3\theta)sin(\theta) = sin(\theta)
\frac{-2sin(3\theta)sin(\theta)}{-2sin(\theta)} = \frac{sin(\theta)}{-2sin(\theta)}
sin(3\theta) = -\frac{1}{2}
sin^{-1}[sin(3\theta)] = sin^{-1}(-\frac{1}{2})
3\theta = -30
\frac{3\theta}{3} = \frac{-30}{3}
\theta = -10

How can you write the equation for a linear function if you know only two ordered pairs for the function?
Vinvika [58]
1. m
2. One set of ordered pairs
3. b

To show why this is, I’m going to explain how to write the equation for a linear function with two random sets of ordered pairs - (1,0) and (5, 8).

First, find the slope. The formula for slope is m = (y2 - y1)/(x2-x1) where m is the slope and (x1, y1) and (x2, y2) are two sets of points.

This is why #1 is m. M is the letter used when finding slope.

To find m, I plug in the two sets of ordered pairs.

m = (8-0)/(5-1)
m = 8/4
m = 2

An equation for a line (linear function) is written in something called slope-intercept form. It looks like y = mx + b. m is the slope and b is the y-intercept (number y equals when x = 0). If m = 3 and b = 1, the equation would be y = 3x + 1.

Here, you have just solved for m and know it equals 2. Plug that value in for m.

y = 2x + b

To solve for b, plug one ordered pair in for x and y. I will use (1,0)

0 = 2(1) + b
0 = 2 + b
-2 = b

Now that you know b = -2, plug that in for b.
y = 2x - 2. Now you have the equation fo the line.

Answer:

sorry i wish i knew how but i would like to give you aomething other than an answer for your question and i hope this is ok.

Step-by-step explanation:

every day is a new day and a new opportunity to change the world no matter how BIG or how small.  even if you make mistakes. always remember this though. whatever you put into the world, whether it be good or bad, it will always come back three times.

meaning that when you do something good something three times as good will happen to you. The same is so for bad except it would be 3 times as bad as will happen to you.   I hope your day is great and may you do many great things.
