Mathematical Functions in C Programming

This video tutorial introduces various math functions available in C programming by including the math.h header file. It covers functions such as square root (sqrt), power (pow), rounding (round, ceil, floor), absolute value, logarithms, and trigonometric functions (sine, cosine, tangent). The tutorial provides examples of how to use these functions and concludes with a call to action for viewers to engage with the content.
