Cosh^2x - sinh^2x = 1

coshx = sqrt( 1 + sinh^2x)
 
= sqrt(1 + (8/15)^2) = 17/15

for tanh

just divide

sinhx/coshx = tanhx = 8/17

for sech , cosech, coth << just flip the original as normal trigonometric functions <span />

A coach purchases 47 hats for his players and their families at a total cost of $302. The cost of a small hat is $5.50. A medium
bazaltina [42]
First, we define variables:
 x: small hat
 y: medium hat
 z: large hat
 We now write the system of equations:
 x + y + z = 47
 5.50x + 6y + 7z = 302
 -3x + y = 0
 We can write the system in matrix form as:
 Ax = b
 Where,
 A = [1  1  1; 5.50  6  7; -3  1  0]
 b = [47;  302;  0]
 x = [x;  y ;  z]
 Solving the system we have:
 x = 6
 y = 18
 z = 23
 Answer:
 
the coach did purchase 23 large hats
 
d. 23

Find the coordinates of the point (x,y,z) on the planez=4x+3y+1 which is closest to the origin.
Nataliya [291]
Given plane &Pi; : f(x,y,z) = 4x+3y-z = -1
Need to find point P on &Pi;  that is closest to the origin O=(0,0,0).

Solution:
First step: check if O is on the plane &Pi; : f(0,0,0)=0 &ne; -1 => O is not on &Pi;
Next:
We know that the required point must lie on the normal vector <4,3,-1> passing through the origin, i.e. 
P=(0,0,0)+k<4,3,-1> = (4k,3k,-k)
For P to lie on plane &Pi; , it must satisfy
4(4k)+3(3k)-(-k)=-1
Solving for k
k=-1/26
=>
Point P is (4k,3k,-k) = (-4/26, -3/26, 1/26) = (-2/13, -3/26, 1/26)
because P is on the normal vector originating from the origin, and it satisfies the equation of plane &Pi;
Answer: P(-2/13, -3/26, 1/26) is the point on &Pi; closest to the origin.
