Please give specific instructions line per line, and all commands necessary to solve and plot on the same graph the inequality (x+3)^2>(-2)*(x+10).Thank you in advance for your help

I'm trying to use solve to find out if a system of equalities and inequalities has any solution or not, but maple 15 seems to be giving phantom solutions.  A simple example is the following:

  solve({ a + b = 1, a > 0, b > 1, c > 0 }, {a,b,c});

It gives the output

Hi,

I want to create a tangent function.

I know that you can create tan(x) but how can you create the tangent function when the solutions are only:

x in [0.19740;0.91510[ union [3.3390;4.0567 ?

Another explanation:

How you can graphically show the valid values of x in this inequality?

                  0.2 ≤ tan x < 1.3
Best regards

How to solve the inequality 3^((x+3)/(5*x-2))-4 >= 5*3^((9*x-7)/(5*x-2)) with Maple?
An exact and explicit solution is required.

How to solve this inequality? 6/(2*x+1)>(1+log[2](2+x)/x). I tried

solve(6/(2*x+1)>(1+log[2](2+x)/x),x);

I receive: "Warning, solutions may have been lost."

i am unable to solve the following inequalities:

ineq1 := (4-(3/2)*q+(1/2)*sqrt(28-24*q+5*q^2))*(1/2-(1/2)*q)

ineq2:=(3-q+(1/4)*sqrt(84-58*q+10*q^2)+(1/4)*sqrt((4-2*q)*(3-q)))*(1/2-(1/2)*q):

solve(ineq1<1,q)

solve(ineq2<1,q)

"Warning, solutions may have been lost"

please help me here

I am a transplant from to Mathematica to Maple and still getting used to things. Could somebody please help me finding the maximum of f with repect to the constraints and with the variables below. I keep getting  syntax error, no matter how many times I check the documentation page. Thank you very much

f:=1/((4 a - 3 M) (-4 b + 3 M)) (-9 M^3 - 16 a b x +
    12 a M x + 12 M^2 x + 16 b x^2 - 12 M x^2 + 12 b M y +
    12 M^2 y - 16 b x y - 16 M x y - 12 M y^2 + 16 x y^2)...
