Question

Решите неравенство sin( 3x/2 + П/12) < 1/ корень из 2. В ответе укажите наименьшее положительное целое число, которое является решением неравенства. Помогите, пожалуйста!

Answer 1

Sin(3x/2  +  pi/12)  <  1/V2
-5pi/4  +  2pin   <  3x/2  +  pi/12  <  pi/4  +  2pin
-4/3pi  +  2pin  <    3x/2    <    pi/6  +  2pin
-8/3pi    +    4pin  <  3x  <  pi/3    +4  pin  
-8/9 pi    +  4/3pi n  <  x  <  pi/9  +  4/3 pin
Ответ.    Наименьшим  положительным  целым  числом  будет  1  градус.

Answer 2

Sin(3x/2+П/12)<1/sqrt2
-5П/4-П/12 +2Пn<3x/2< П/4-П/12+2Пn
-8П/9+4Пn/3<x<П/9+4Пn/3
П/9=20 градусам
-8П/9=-160 градусов
Так как надо найти положительное решение, то оно будет в интервале от 0 до П/9=20, а так как это решение целое и наименьшее, то это 1 градус, что равно П/180 радиан

Answer 3

Solving the Inequality

To solve the inequality sin(3x/2 + π/12) < 1/√2, we can follow these steps:

Step 1: Determine the range of values for x that satisfy the inequality. Step 2: Find the smallest positive integer value of x that satisfies the inequality.

Let's solve the inequality step by step.

Step 1: Determining the Range of Values

To find the range of values for x that satisfy the inequality, we need to find the values of x that make the expression sin(3x/2 + π/12) less than 1/√2.

The inequality sin(3x/2 + π/12) < 1/√2 can be rewritten as sin(3x/2 + π/12) - 1/√2 < 0.

To solve this inequality, we can use trigonometric identities and properties. However, since the given inequality involves a specific value of 1/√2, it is more convenient to use a calculator or a graphing tool to find the range of values for x.

Using a graphing tool, we can plot the graph of the function y = sin(3x/2 + π/12) - 1/√2 and find the values of x for which the graph is below the x-axis.

Unfortunately, I cannot provide a graph here, but you can use a graphing calculator or software to plot the graph and find the range of values for x.

Step 2: Finding the Smallest Positive Integer Value of x

To find the smallest positive integer value of x that satisfies the inequality, we need to determine the smallest x value within the range found in Step 1.

Since I cannot provide the exact range of values for x, I recommend using a graphing calculator or software to plot the graph and find the smallest positive integer value of x that satisfies the inequality.

Please note that the range of values for x may be an interval or a combination of intervals, depending on the graph of the function.

I apologize for not being able to provide a more specific answer, but I hope this explanation helps you understand how to approach solving the inequality.
