Find the the sum for the shown infinite geometric series? 2,2/3, 2/9, ...

Mathematics

Answer:

3

Step-by-step explanation:

The formula for the sum of an infinite geometric series is

\frac{a}{1-r}

Where a is the first term and r is the common ratio. We can see that the first term is 2, and to find the common ratio, we can divide a term by the one before it. We can get:

\frac{\frac{2}{3}}{2} =\frac{2}{3} *\frac{1}{2}=\frac{1}{3}

Now, we have all the values need to evaluate the formula. We can plug them in:

\frac{2}{1-\frac{1}{3} } \\\frac{2}{\frac{2}{3} } \\2*\frac{3}{2}\\3

Use basic trigonometric identities to simplify the expression: sin (-x) cos (-x) csc (-x) =?
Anestetic [448]

Answer:

sin (-x) cos (-x) csc (-x) =cos(x)

Step-by-step explanation:

We know by definition that the cosine is an even function, therefore

cos (-x) = cos (x)

We also know that the sin is an odd function, therefore

sin (-x) = -sin (x)

By definition:

cscx = \frac{1}{sinx}.

Then:

csc(-x) = \frac{1}{sin(-x)}.

csc(-x) = -\frac{1}{sin(x)}.

Using these trigonometric properties we can simplify the expression

sin (-x) cos (-x) csc (-x)= -sin(x)cos(x)*(-\frac{1}{sin(x)})\\\\sin (-x) cos (-x) csc (-x)=cos(x)
