I thought the maths area would be the best place to ask..
What kind of function would represent a 3 dimensional sine wave?
A sine wave, where the z-axis lays on the circumference of a circle.
Maxima word problem -- Not sure about my answer.
This was in an assignment handed out after our introduction to extrema's.
A builder wants to build a small building consisting of 4 walls and a roof (all rectangular). The cost of the bricks for the walls will be $25/square metre, while the roof...
Prove:
\frac{CosθSinθ}{1 + Tanθ} = Cos2θ
===========================
I multiply out the denominator to get:
CosθSinθ = Cos2θ + CosθSinθ
I cannot seem to prove it.
Starting to think it's a trick question.. :/
The amount of water in a tank doubles every minute. If the tank was full at the 1 hour mark, when was the tank half full?
=============================
It's not homework, I'm just trying to get the actual (reasoned) answer..

Here is the answer I argued (though...
A block is sliding down a 30° incline at 1.2ms^-2
Find the coefficient of static friction.
[g=9.8ms^2]
I am stumped..
Some relevant equations:
Fr = μ(Fn)
Fn = mg
Ultimately I got μ=0.5 ---> This was through mashing and playing with some trig.

A 1.6 kg block is pushed into a spring with spring constant of 1.0 x 10^3 N/m. The spring is compressed a distance of 2.0 cm [0.02m], and the block is released from rest in the horizontal direction.
(a) Calculate...
G'day, i am new here, and have quite a profound lust for maths/physics.
This simulator is brilliant, though i am not sure how accurate the simulation represents gravitational equations.
