Your calculation for Uy is overly complicated. Uy = 50sin(30) = 25. The calculation other than that is correct it seems you plugged the wrong numbers in the calculator. The working out seems set out in odd way. a = -9.8 has it is acting down not up. Your Vy seems to be the initial velocity in...

It is 3^n - 2^n.

Data science is used in medicine and health. Areas that could be useful include NLP, computer vision. Any classification or regression task. The degree to which your knowledge of medicine will be useful, I don't know.

You could do it. Not sure how it will go.

Have you consider studying data science and becoming a doctor.

TAFE is a pathway to a degree. There are also other pathways depending on what you are interested in e.g. UTS College. Do research. Also nothing is stopping from completing an online degree. All the best.

TAFE

Just use inspection. What happen as x -> 1 or infinity or 0. Review limits if need be. There various definitions that form limits. You need to combine them. e.g. standard definition, one sided, infinite limits, limits at infinity.

Questions: What will happen to the gradient as x->infinity or x->-infinity? When is the gradient positive or negative?

Yes k needs to be integer. nCk is just the number of permutations in binomial theorem. Let say you want find the number permutation of XXXYY. That is just 5C3 if you choose 3 X's or equivalently 5C2 if you choose 2 Y's. As an exercise take a look at multinomial distribution

Most likely coming from chain rule. Whenever the thing you are taking derivative of is not in the proper chain rule is required. In this case let u = tan^-1(x/3) To keep things simple try finding first d/dx (tan^-1(x/3)) use a online differentiation calculator if need be.

The equal sign at (a) is incorrect.The trigonometric addition/subtraction angle identity has not been applied properly. Have another look at them again.

It is not exactly clear what are trying to ask. What ratio do you want the amplitude to be with respect to half the period. 1:180 or 1: i Presuming want the former than: y' = pi/180 * cos(x) This more complicated than if ratio is 1: i. As if you let pi radians = 180 degrees, you will end up...

Assuming you are not accelerated or anything you should 2 be taking Advanced Math. If you are accelerated you should have taken 2 unit HSC exam in the past

You don't need to draw the parallelogram in this question. Maybe the opposite sides are not parallel who knows. You just need to find the distance. Distances are equal.

I will try to explain in words. So if (x, y) is a point in function f. Then (y, x) is a point on f^-1. The unit circle definition of sin is sin theta = y. The domain is given by -1 <= x <= 1. Using this domain we can determine the range of x^2 which in turn help us determine the range of...

By inspection -1 <= x <= 1 => The smallest value of x^2 is 0 and the largest is 1 You need to examine the domain.

Note: Not from USYD or familiar with economics what it's like to study them and how useful they each might be? Data science is data science. stats is stats If you want become data scientist then go with that. If you think stats might be useful for certain careers go with that. Data Scientist...

-1 <= x^2 <= 1 => -1 <= x <= 1 You need to take an inspection based approach for calculating range. The smallest value of x^2 is 0 and the largest is 1.

Cannot answer about effort as the only job I have ever done is an internship. It is not too bad. Don't know much about leadership opportunities but it is possible to move up ladder of course. Maybe search people up on Linkedln in manager or leadership roles to see skills.
