Squaring a function just means to calculate the result of the function and square the result. (Usually. Sometimes it means to apply the function again to the result, but I doubt that’s the case with tanh, or any trigonometric function, as it wouldn’t make sense.)

```
#include <math.h>
float tanhX = tanh(x);
float tanhSquaredX = tanhX * tanhX;
```

Anybody can tell me how to write C code equivalent to this?

tanh2 (x)That would mean the

hyperbolic tangent squared of X.Never heard of ‘squared’ functions before.

How do I translate that to C?

Thanks in advance.
