The diagram is a little bit off but mostly correct. The angle of depression or elevation is done with respect to a horizontal line. In your diagram 30 degrees would be the angle of depression instead of 20 degrees. You will find the second building has greater height than the first due to the...

Sorry how did you get this part: i|z^2|=\frac{1}{4}z^4 where \Re(z^4)=0

Where did you get the question from?

So you have not written coherently. I am not 100% sure however I think Karush-Kuhn-Tucker condition is what you are after given you have additional constraint x != 0. Not sure how to solve it otherwise.

I am not sure if he is taking students,however I think @Hivaclibtibcharkwa might be worth looking into.

@T_Brendan_T Here is what I think. Note I have not studied engineering studies. force = mg*sin(theta) # need to know about mgsin(theta) and mgcos(theta) => a = g*sin(theta) => v = integral(g*sin(theta))dt => v = gsin(theta)t + C = gsin(theta)t # We assume...

@jimmysmith560 do you have an answer?

So you can always change degrees or do another degree if desired. Maybe doing double degree could be the answer or a degree with flexible major.

So you are correct. I get the feeling there were some issues with the working out present. The work below uses content from 4 unit math projectile motion. You will see some of the calculations from marker are incorrect. I am bit concern by rounding that was done in the intermediate steps however...

sinusoidal. Basically trignometric. As I am not well versed in physics and don't know exact context of the question I am not able to give a better answer.

I would recommend @Drongoski as a 1 on 1 tutor. Not sure if he is taking students though.

So if they are in distinct groups as in two different circle then you would get: 3! * 3! due to rule of product axiom.

So the integrand is area of the cross section. So just integrate that.

Use an online integral/differentiation calculator

The issue is it not clear what you have tried. Maybe try stackoverflow or geeksforgeeks. Make sure to use a tag. e.g. [tktinker] or [python].

Any side of a triangle is greater than or equal to the difference between the other two sides flags: it is similar to the triangle inequality. cannot think of a particular question. https://en.wikipedia.org/wiki/Triangle_inequality

Yes, In mathematics, the complex conjugate root theorem states that if P is a polynomial in one variable with real coefficients, and a + bi is a root of P with a and b real numbers, then its complex conjugate a − bi is also a root of P https://en.wikipedia.org/wiki/Complex_conjugate_root_theorem

Sorry I messed up refer to Drogonski's answer

If you want you could try completing the square to double check your answer. Completing the square and the quadratic formula are equivalent.

https://www.westernsydney.edu.au/currentstudents/current_students/dates/dates/census_dates generally I think it is after the census date you are no longer allowed enroll in other subjects. That being said you can drop subjects after the census date, however, you will still incur the fee for...
