I'm trying to graph this function but it comes out a straight line.

Thanks in Advance.

plot(cos(Pi/4), -2*Pi .. 2*Pi)

plot(cos((1/4)*Pi), -2*Pi .. 2*Pi)

Hi,

I'm trying to solve for Double Inequality. (1.1) and (1.3) combined.

Thanks in Advance
 

Example: Solving a Double Inequality

 

-3 <= 6*x-1

0 <= 6*x+2

(1.1)

"(->)"

[[-1/3 <= x]]

(1.2)

6*x-1 < 3

6*x < 4

(1.3)

"(->)"[[x < 2/3]]

"ex1(x):=6 x-1"

proc (x) options operator, arrow, function_assign; 6*x-1 end proc

(1.4)

"->"

 

"->"

"ex2(y):=3"

proc (y) options operator, arrow, function_assign; 3 end proc

(1.5)

"ex3(y):=-3"

proc (y) options operator, arrow, function_assign; -3 end proc

(1.6)

NULL

Hi,

I was wondering is there an easier way for me to solve an Equation Involving an Absolute Value?


 

Example: Solving an Equation Involving an Absolute Value

 

x^2-3*x = -4*x+6

x^2-3*x = -4*x+6

(1.1)

"(->)"

[[x = 2], [x = -3]]

(1.2)

-x^2+3*x = -4*x+6

-x^2+3*x = -4*x+6

(1.3)

"(->)"

[[x = 1], [x = 6]]

(1.4)

"ex7(x):=|x^(2)-3 x|+4 x-6"

proc (x) options operator, arrow, function_assign; abs(x^2-3*x)+4*x-6 end proc

(1.5)

"->"

Hi,

I'm only getting one Answer instead of two (see below).

Thanks in Advance


 

Example 4: Solving Equations Involving Radicals

 

"ex4a(x):=sqrt(2 x+7)-x-2"

proc (x) options operator, arrow, function_assign; sqrt(2*x+7)-x-2 end proc

(1.1)

"->"

 

NULL

NULL

sqrt(2*x+7)-x-2

(2*x+7)^(1/2)-x-2

(1.2)

"(->)"

[[x = 1]]

(1.3)

NULL

2*x+7 = x^2+4*x+4

2*x+7 = x^2+4*x+4

(1.5)

x^2+2*x-3 = 0NULL

x^2+2*x-3 = 0

(x+3)*(x-1) = 0

(x+3)*(x-1) = 0
