I have a curve Tractrix: x(t)=1/cosht,y(t)=t-tanht

how I do?

• Find the length of the tangent line from the tangent point to the asymptote
• find the area between the curve and its asymptote
• find the length of the curve from x-axis to a point on the curve
• find the slope of the tangent line at any point along the curve

I hope you can help , its very important to me

consider the line y=-x+1 on xy plane. the shortest line from the origin to y=-x+1 intersects with it at (x*,y*)=(0.5,0.5). Confirm this result by formulating and solving and optimization problem. 

Write a procedure that determines the solutions of a quadratic equation from inputs a, b and c by using the discriminant and the quadratic formula. The quadratic equation procedure should be able to solve all cases: invalid input, linear case, real and complex roots. The procedure should also plot the given equation.

Find the principal arguments of the 5 roots of the polynomial:p(z)=z^5-5*z^4-5*z-5,and enter a decimal approximation to the largest principal argument in the box below.  Your approximation should be correct to 10 significant figures

Can some one tell me how to write in maple？correct answer is 2.691121659

Question :

Write a procedure that determines the solutions of a quadratic equation from inputs ,  and  by using the discriminant and the quadratic formula.

The quadratic equation procedure should be able to solve all cases: invalid input, linear case, real and complex roots. The procedure should also plot the given equation.

I dont understand how to do this can someone please please do it this for me urgently required.

A := Matrix([[5, 4, 5, 4, 8, 4, 6, 1, 4], [2, 8, 4, 7, 5, 1, 9, 6, 1], [8, 4, 9, 8, 8, 8, 6, 2, 8], [7, 1, 8, 6, 6, 5, 3, 7, 7], [8, 7, 9, 4, 7, 8, 2, 7, 4], [5, 1, 7, 8, 5, 7, 2, 2, 8], [7, 4, 1, 7, 7, 1, 7, 8, 6], [2, 9, 9, 4, 7, 5, 2, 6, 8]]);

Create the vector b that is column 7 from A and the matrix C that is made from columns 1 to 6 and 8 to 9 of A (in the same order as the columns of A

I have 2 questions that I can solve by hand, but I need to show how to solve using maple.

1. Solve for y: dy/dx = -y/x ; y(1)=-1

2. Indicate at each of the twenty-five points specified on the graph frame to the right (this is just a x=-2..2 and y=-2..2 graph with a 25 point grid) what the slope of the solution curve to y'=y is at that point.  Sketch the curve for the initial condition y(0)=0. The indicated points are at the (x,y) points from...

i have this unfinished procedure to multiply two matrices 

multmatrix:= proc(A:matrix)

local m,n,i,j,r,c,t,a;

m:=linalg[rowdim](A);

n:= linalg[coldim](A);

i:=linalg[rowdim](B);

j:=linalg[coldim](B);

K:=array(1..m,1..n);

H:=array(1..i,1..j);

I hope this is the right place to ask, as the links for Maple Student Help were dead. I'm trying to assign a range of values to a name in order to solve questions about binomial distribution using variations of the function shown below:

I have the fractcal of a snowflake

Use Newton’s Method to approximate the indicated root of the equation to correct six decimal places.

The root of 2.2x⁵ – 4.4x³ + 1.3x²-0.9x-4.0=0 in the interval [-2, -1].

The rest of the assignment states : "

Start by plotting the function in
Maple to get a reasonably good initial approximation. You may use a
“while” loop, but do not use existing Maple commands for Newton’s

A  group of boy and girl students  compete to eat pizza at super market .One pizza was cut 12 pieces one boy student  could to eat 6 or 7 pieces and one girl student could to eat 2 or 3 pieces .

If they put  4 pizzas they will not see enough  if  they put 5 pizzas will over .

How many boy and girl students who compete ?

Write a procedure, primesum, whose input is a positive integer n and whose output is the sum of all primes p such that p is less than or equal to n. You may use th built-in procedure isprime.

i need to write a program for my calculator to solve these eqution
