Given the inequality:
−acos(x)+asin(x)>0To solve this inequality, we must first solve the corresponding equation:
−acos(x)+asin(x)=0Solve:
x1=0.707106781186548x1=0.707106781186548This roots
x1=0.707106781186548is the points with change the sign of the inequality expression.
First define with the sign to the leftmost point:
x0<x1For example, let's take the point
x0=x1−101=
−101+0.707106781186548=
0.607106781186548substitute to the expression
−acos(x)+asin(x)>0−acos(0.607106781186548)+asin(0.607106781186548)>0-0.265967334228303 > 0
Then
x<0.707106781186548no execute
the solution of our inequality is:
x>0.707106781186548 _____
