The period of the function tan(3x+5) is:
I: The modulus of √3+i/(1+i)(1+√3i) is 1/√2
II: The least positive value of n for which (1-i/1+i)n=1 is 2
If 1,ω,ω2 are the cube roots of unity, then (a+bω+cω2)/ (c+aω+bω2) is equal to:
If (cos 3α+i sin 3α)(cos 5β+i sin 5β)= cos θ+i sin θ then θ is
If x+iy= cis α cis β then the value of x2+y2 is
