graph each equation for the interval -360 is less than or equal to x and 360 is greater than or equal to x: y=1/2cos(2x+60)

lianna [129]

Answer:

See graph

Step-by-step explanation:

We want to graph $y=\frac{1}{2}\cos(2x+60\degree)$ on the interval $-360\degree \le x \le 360\degree$

We need to plot some few points

$(-30\degree,\frac{1}{2})$

$(-15\degree,\frac{\sqrt{3}}{4})$

$(0\degree,\frac{1}{4})$

$(15\degree,0)$

$(30\degree,-\frac{1}{4})$

$(45\degree,-\frac{\sqrt{3}}{4})$

$(60\degree,-\frac{1}{2})$

$(75\degree,-\frac{\sqrt{3}}{4})$

$(90\degree,-\frac{1}{4})$

$(105\degree,0)$

$(120\degree,\frac{1}{4})$

$(135\degree,\frac{\sqrt{3}}{4})$

$(150\degree,\frac{1}{2})$

This will give us one cycle.

We then use the pattern to complete the graph on the interval

$-360\degree \le x \le 360\degree$

What is 0.25 in scientific notation ?

andriy [413]

The scientific notation of 0.25 is 2.5 x 10⁻¹

Scientific notation is used to handle numbers that are very big or very small.

It has 3 parts, the coefficient, the base and the exponent.

There must be 1 digit before the decimal point in the coefficient.
10 is always the base
the exponent signifies the number of places the decimal has moved from its original location to the location before 1 digit. Positive exponent signifies that the decimal point is shifted to the right. Negative exponent signifies that the decimal point is shifted to the left.

In the above scientific notationl

2. 5 is the coefficient
10 is the base
-1 is the exponent. the decimal point shifted one place to the left.
