Hi, can someone please help me..
Question: Write the function in the form , with u and v real functions. Hence show that f(z) is an entire function.
here's my working:
then i do partial derivaties to satisfy cauchy riemann equations..
partial of u wrt x = 0
partial of v wrt y = cos 2x i sin iy - 2i sin 2x cos 2iy
partial of u wrt y = 0
partial of v wrt x = ..
well i know i did it wrong coz the following are meant to be satisfied, but they just don't work out:
partial of u wrt x = partial of v wrt y
partial of u wrt y = - partial of v wrt x
so can someone please help me??
