Hello, everyone!

I was given this week's Maple assignment in my class and I've come across a problem. I'll say this now so I don't get sent away, I am NOT asking for the answer. For this question there is a part A and part B, but also a preliminary check to make sure our code is wokring (as seen in the picture link). The issue I'm here for is that I can't figure out the code for the preliminary check... I've been here for hours and I'm stumped.

This is my attemp so far; 

f := x^(6*ln(x))

Digits:=15;

T2 := convert(%, polynom)

f_value := evalf(subs(x = 5, T2))

I'm very confused what to do next in order to get that preliminary test amount of 5121425.461.

Thanks in advance! :)

Hey, everyone!

Given the following equation: 

 I need to plot the graph when x₁ = 0.4.. How can I do that?

I managed to plot f(x) just fine, just not sure how to plot Newton'sMethod at x₁ = 0.4.

Thanks in advance! :)

g := (1/8)*x*sin(13/x)+arcsin(5*x^2/(8*x^2+1))

G := unapply(g, x)

H(x) :=G(G(x))

I need to find the value of H'(pi/2). I tried this, but it didn't work;

simplify(eval(diff(H(x), x), x = (1/2)*Pi))

Will it not work for this type of question? 

Thanks :)

f(x) :=(x^(12)-x*sin(x^(11)))/(x^(34))+e^(sqrt(x+4))*ln(abs((cos(x)^(5))-6))

diff(f(x), x$2)

What would I need to type in if I would want to find f^-2(5)? I've tried this;

diff(f(5), x$2)

But it keeps giving me zero... Thanks in advance! :)

This is going to sounds so stupid probably, but I'm a newbie with the software and I really am clueless at the moment.

I was asked to define given information as a function, then sub -25 in for x to verify I typed the function correctly. But it's not working.. (I have a screenshot saved to my computer, but apperently I can't post it).

f(x) :=(x^(12)-x*sin(x^(11)))/(x^(34))+e^(sqrt(x+4))*ln(abs((cos^(5)x)-6))

This is my function...how do I check what value f(-25) will give me? When I calculate it (first with evalf, then without) it only showed another function as the answer, rather than the answer..sigh, I'm terrible with this software.
