How to...live script

Develop a live script to calculate:

𝑁= ((5x-2)*ln(sqrt(x))) / ((x^(2)-1)*(sin(x)))

Calculate N when

(a) x = 2.4,

(b) x = 12.1,

(c) x = 0.07,

and (d) x = 1.

What have you attempted?

This sounds like a homework assignment. If it is, show us the code you've written to try to solve the problem and ask a specific question about where you're having difficulty and we may be able to provide some guidance.

If you aren't sure where to start because you're not familiar with how to write MATLAB code, I suggest you start with the MATLAB Onramp tutorial (https://www.mathworks.com/support/learn-with-matlab-tutorials.html) to quickly learn the essentials of MATLAB.

If you aren't sure where to start because you're not familiar with the mathematics you'll need to solve the problem, I recommend asking your professor and/or teaching assistant for help.

x=2.4
N=((5*x)-2)*(log(sqrt(x)))/(x^(2)-1)*(sin(x))

I've tried a couple equations and checked with my calculator for all and none have worked. This equation is the closest I've got.

I'm just struggling on how to translate the equation from the hw onto matlab.

[Walter Roberson]

Could you post an image of the equation to be programmed ?

When you're checking with your calculator, are you taking the sine of x in degrees (for which the corresponding function in MATLAB would be sind) or in radians (for which sin is the correct function)?

You should also be careful with your parentheses.

x1 = 1/(2)*2 % divide 1 by 2 and multiply the result by 2 = 1
x2 = 1/(2*2) % multiply 2 by 2 and divide 1 by the result = 0.25

I've checked both in degrees and radians mode. Idk what else to do with my parenthesis, I feel like I've tried everything. thanks though.
