U guys are smart but i am not... i need help, please help me
thank you :)
find lim y. and lim y x->infinity. x-> negative infinity 1.) y= (x + sinx)/x 2.) y= x/ (1+ 2^x)
thank you guys so much! I had a really hard time with these. I appreciate it :)
1.) determine two pairs of polar coordinates for the point (-4sqrt3, 4sqrt3)with 0degrees less than or equal to theta less than or equal to 360degrees 2.) Use DeMoivre's Theorem to find (1-i)^10. write your answer in the form a+bi. 3.) Find the cube roots of -8. Write your...
find the cube roots of the complex number. 27((cos(11pi/6)) + i(sin(11pi/6))
I dont see the link. I dont think this website allows you to put up links
express the roots of unity in standard form a+bi. 1.) cube roots of unity 2.) fourth roots of unity 3.) sixth roots of unity 4.) square roots of unity
