The discussion focuses on using the pow function from the math.h library in C to express trigonometric functions. It clarifies that sin2(x) and (sin(x))^2 are identical and can be computed as sin(x) * sin(x). However, sin(x^2) is distinct, representing sin(x * x), which is computationally more efficient than using pow. The pow function is defined as double pow(double x, double y), where x is raised to the power of y.

Since all of these expressions involve only the power 2, you can get the same result by multiplying instead of using the pow() function. For #2 above, sin(x^2) is the same as sin(x * x), but the latter form takes considerably less time to compute.pairofstrings said:Hello.
How to write
1. sin2(x)
2. sin(x2)
3. (sin(x))2
by using predefined function pow defined in math.h in C language?
Are they all same?
Thank you.
