hi!Here is a copy of our wiki pages on the topics allotted to us i.e. difftime,ccos and sinh.I am doing this project with prakriti kar.prakriti(talk)

=difftime=

INTRODUCTION
The C language provides us with difftime function which returns the time elapsed between two calendar dates. This function is defined in the header file time.h. It returns the difference (t2 - t1), where t1 is initial time and t2 is end time in seconds as a double-precision floating point number. This function is significant because there are no general arithmetic operations defined on type time_t. =sinh(C)=

INTRODUCTION
Sinh stands for hyperbolic sine.This function in C language computes the hyperbolic sine of a given input.This function is defined in the header file math.h. This function has a double-precision floating point number as the input. This function returns hyperbolic sine of given input. If the return value is too large then sinh sets errno to ERANGE and returns HUGE_VAL or HUGE_VALF or HUGE_VALL which has the same sign as that of the input by default. =ccos=

INTRODUCTION
The C programming language provides with the ccos function which gives the cosine of a complex number.It is included in the header file complex.h.This function returns a double-precision floating point number.
