Find the coordinates of the point (a, b).

Leviafan [203]

Answer:

a = $\frac{1}{\sqrt{2} }$ and b = $\frac{\sqrt{2} }{2}$

Step-by-step explanation:

As we know, the radius of the unit circle is 1 unit (it is the hypotenuse in the right triangle, the blue line)

We use trigonometric formulas to find out a and b

Sin(45) = opposite side / hypotenuse

<=> Sin(45) = b / 1

<=> b= Sin(45)*1 = $\frac{\sqrt{2} }{2}$

Cos(45) = adjacent side / hypotenuse

<=> Cos(45) = a / 1

<=> a = Cos(45)*1 = $\frac{1}{\sqrt{2} }$

So: a = $\frac{1}{\sqrt{2} }$ and b = $\frac{\sqrt{2} }{2}$

vladimir1956 [14]

Step-by-step explanation:

The exact question is as follows :

Given - The value of π up to 35 decimal places is given below:

3.14159265358979323846264338327950288

To find - Make a frequency distribution of the digits 0 to 9 after the decimal point.

Proof -

The Frequency Distribution Table for digits after decimal point in the value of Pi is :

Digits Frequency after decimal point

0 1

1 2

2 5

3 6

4 3

5 4

6 3

7 2

8 5
