Why is `evalf` not working?

Why is evalf not changing $\pi$ and $e$ to floating point in the following: h := proc (x) options operator, arrow; exp(x)*cos(x) end proc Tay := taylor(h(x), x = (1/6)*pi, 2) P2 := convert(Tay, polynom) evalf(P2(.5)) The output…

Changing Rational Expressions into a Sum (or Difference) of Rational Expressions in Maple

Given $\dfrac{x^4+x^3-4x^2-4x}{x^4+x^3-x^2-x}$, is there a way to make it into a sum or difference of rationals such as: $\dfrac{x^2}{(x-1)(x+1)}-4\dfrac{1}{(x-1)(x+1)}?$ I've tried using factor and normal but with no luck. I think the closest I've…

Optimization in maple

I optimized a function and I want to use the value. The answer I got is [4.77011197468878567, [alpha = 1.43792823465135400]] and I want to use the alpha for plotting but I don't know how to extract it.

How to cancel the same term on both sides of equation in Maple?

I tried using "simplify" but it doesn't work. For example: simplify(a*b=b*c) assuming b>0 will not get a=c but return the original equation. or even simplify(a*b/b) assuming b>0 will not get a directly but return the original equation. Could anyone…

How to interpret a solution from Maple's $solve$ command when I use $assume$?

Consider the following function $$W(k,a,b,q_1,q_2,q_3,q_4)=\frac{k}{a}(q_1q_3+q_2q_4)+\frac{k}{b}(q_1q_2+q_3q_4)+\frac{k}{\sqrt{a^2+b^2}}(q_2q_3+q_1q_4)$$ In Maple, W := (k, a, b, q__1, q__2, q__3, q__4) -> k*(q__1*q__3 + q__2*q__4)/a + k*(q__1*q__2…

Evaluate integral Maple

I am trying to solve the following diff-equation: $y'(t)−(3t+2)y(t) = 4e^{3t}$ I have found the solution manually and now I want to check my answer with Maple. I have defined the diff-equation: L := D(y)(t) - (3t^2 + 2)y(t) = 4exp(3t) Then I have…

Why can't DEplot plot the part of a solution to a differential equation to the left of a singularity?

I'd like to plot the solution to the differential equation $$\frac{d}{dx}y(x)=\frac{(y-1)^2}{(x+1)^2}$$ with initial value condition $y(0)=0$. The solution is $$y(x)=\frac{x}{2x+1}$$ Clearly, this function is not defined for $x=-\frac{1}{2}$, a…

How to plot a paraboloid in Maple using spherical coordinates?

I am studying spherical coordinates. Here is the equation of a paraboloid in rectangular coordinates $$z = x^2 + y^2$$ In spherical coordinates $$\rho \cos(\phi)=\rho^2 \sin^2(\phi) \implies \rho (\rho \sin^2(\phi)-\cos(\phi))=0$$ So here is what I…
