sinx-10>0 inequation

A inequation with variable

The solution

You have entered [src]
sin(x) - 10 > 0
sin(x)10>0\sin{\left(x \right)} - 10 > 0
sin(x) - 10 > 0
Detail solution
Given the inequality:
sin(x)10>0\sin{\left(x \right)} - 10 > 0
To solve this inequality, we must first solve the corresponding equation:
sin(x)10=0\sin{\left(x \right)} - 10 = 0
Solve:
Given the equation
sin(x)10=0\sin{\left(x \right)} - 10 = 0
- this is the simplest trigonometric equation
Move -10 to right part of the equation

with the change of sign in -10

We get:
sin(x)=10\sin{\left(x \right)} = 10
As right part of the equation
modulo =
True

but sin
can no be more than 1 or less than -1
so the solution of the equation d'not exist.
x1=πasin(10)x_{1} = \pi - \operatorname{asin}{\left(10 \right)}
x2=asin(10)x_{2} = \operatorname{asin}{\left(10 \right)}
Exclude the complex solutions:
This equation has no roots,
this inequality is executed for any x value or has no solutions
check it
subtitute random point x, for example
x0 = 0

10+sin(0)>0-10 + \sin{\left(0 \right)} > 0
-10 > 0

so the inequality has no solutions
