For each complex number z, find Re z (real z), Im z (imaginary z), and magnitude of z.
1. z = e^(1-2i)
2. z = i^(1/2)
3. z = i^i
4. z = tan(i)
5. z = [(1-i)/(2^(1/2))]^40
Im not really sure how to
-5 + 7 |1 - 3b| > 114
im a little confused on how to do this step by step. can anyone help? thanks!-−5 + 7|1−3b| > 114
7|1−3b| > 119
|1−3b| > 17
1−3b 17
−3b 16
b > 6 or b
The perimeter of a rectangular garden is 374 feet. If the length of the garden is 99 feet, what is its width?
__________________
Please Help-perimeter is l + l + w+w = 374
2l + 2 w = 374
2*99 + 2w
Hello Everyone,
Heres the problem:
Find dy/dx by implicit differentiation.
sqrt(7x+y) = 9+(x^2y^2)
sqrt = square root
(x^2y^2) = x squared times y squared, just to clarify.
Thanks everyone, best a
a=4 and b=3
and Im looking for explanation, not just answer =P Thanks!-Well, lets put the numbers in:
2 sin (4y) cos (3x) = 1
Implicit differentiation means we just differentiate both sides of the eq

Please help me with this. Please show your work so I can understand. Thank you.
Also is there a difference between 6+3-2(without quotes) and 6+3-2(with quotes).-2+9^1/2 = 2+(9)^(1/2) = 2+{(3^2

Any help would be greatly appreciated! I have a test tomorrow and do not understand this content :(-Since youve been given a zero, (x - 2/3) or (3x -
Find the values of a and b that make f continuous everywhere:
f(x) =
(x^2 - 4)/(x - 2)if x

Thanks so much!!!! :)-We can rewrite this as
f(x) = x + 2 if x

A publisher decides that each page in a new book must have an area of 73.125 in^2, a 0.75 in. margin at the top and at the bottom of each page, and a 0.5 in. margin on each of the sides. What should t
Find the equation of the tangent line to the curve y=x*(sqrt (x) ) at the point (4,8)?
y=?-y = x*sqrt(x) = x*x^(1/2) = x^(3/2)
--> y = (3/2)x^(1/2) = (3/2)sqrt(x)
At x = 4. y = (3/2)sqrt(4) = (3/2)*2
