Divide. 1+4i 1+21' 1+41' 1+2i=D (Simplify your answer. Use integers or fractions for any numbers in the expression. Type your answer in the form a + bi.) Write the complex number in trigonometric form r(cos 0 + i sin 0), with 0 in the interval [0 , 360). 5 . . ' 5 = cos + isin ) (Type the value for r as an exact answer, using radicals as needed. Type the value for 0 as an integer or decimal rounded to the nearest tenth as needed.)For the vector r = ( - 8, - 4), find - 6r. - 6r=Solve the equation by using the square root property. The solution set is (Simplify your answer. Use a comma to separate answers as needed. Express complex x2 = -25 numbers in terms of i.)Find the magnitude and the positive direction angle for u. U= (7, -24) . . . |u| = 0 = (Round to the nearest tenth as needed. Use angle measures greater than or equal to 0 and less than 360.)For the complex number shown to the right, give (a) its rectangular form and (b) its Aimaginary trigonometric (polar) form with r> 0, 0 0
