[GLSL] no matching overloaded function for cosine and sine

OpenGL OpenGL: Basic Coding
1

I’m coding a shader in GLSL and I need to use sine and cosine functions.
The problem is that I obtain this error compiling the shader:


error(#202) No matching overloaded function found: cos

I look on the web and I found that there exists these definitions:


float cos(float angle)  
vec2 cos(vec2 angle)  
vec3 cos(vec3 angle)  
vec4 cos(vec4 angle)

I want to use the scalar one, and this is the code that generate the error:


#version 450
[...]
layout (location = 6) uniform float angleY;
[...]
void main()
{
    [...]
    float cosangY = cos(angleY);
    [...]
}

I also tried to compute the cosine on a constant value (instead of a uniform variable) but the same error is generated.


#version 450
[...]
void main()
{
    [...]
    float XXX= cos(0.0);
    [...]
}

I’m a beginner in both shading and OpenGL, what I’m doing wrong in my code? Thanks

Solved
I miss that I’ve redeclared “cos” and “sin” identifiers
