Consider five points A, B, C, D and E such that ABCD is a parallelogram and BCED is a cyclic quadrilateral. Let \ell be a line passing through A. Suppose that \ell intersects the interior of the segment DC at F and intersects line BC at G. Suppose also that EF=EG=EC. Prove that \ell is the bisector of angle DAB.

Hi,
Could you solve the equation z^(2) = sqrt(3) - 3*i. Please answer in the form z = x + i*y.

* = multiply with
sqrt = square root

Use these this rules in finding the derivative. Derivative of a constant, Derivative of a power, Derivative of a constant times a function, Derivative of sums and differences, Derivative of a product, and Derivative of a quotient.

Find the indicated derivative

1. y = 4x^5 – 3x^4 + 2x^3 – x + π, dy/dx
2. y = (3w^2 – 4)(3w^2 + 4), dy/dw
3. y = t^2 – 6t + 9/t^2 – 5t + 6, dy/dt
4. w = (t + 1)(t^2 – 1)/t^2 + 2t + 1, dw/dt
5. y = x^3 – 125/ x^2 + 5x + 25, dy/dx
6. y = (x / x+ 1 + x – 1 /x ), dy/dx
7. x = (t + 1)(t + 2)(t + 3), dx/dt
8. y = (1/x + 1/x^2 + 1/x^3), dy/dx

Why when you take any number
after that double it by two
and then plus 100
after that divide by two
and then minus back the number that you think
you will get the answer 50.

Explain through this equation.
(A x B + C )/B - A= C/B

the sign "/" means divide.

Decompose v into two vectors (vector 1 and vector 2), where vectors 1 is parallel to w and vector 2 is orthogonal to w.

What does the word orthogonal mean here?

Also, what does the question mean by decompose?

(1) v = -3i + 2j, w = 2i + j

(2) v = 1 - 3j, w = 4i - j

Find the dot product v times w and the angle between v and w.

(1) v = i + j, w = - i + j

(2) v = i + sqrt{3}(j), w = i - j

What exactly is the angle between them anyway?
