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.

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

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.
