efficiency = Energy out/Energy in
efficiency = 300/1000 = 0.3 or 30%
However, your energies don't balance 300 + 9650 + 70 > 1000
6ml = 0.006l
There are 1000 millilitres in a litre.

Neither; in general it's just a number.
tanh(x) = (ex - e-x)/(ex + e-x) x doesn't have to be an angle.
x = 3 (y = 0) is certainly a solution, but x = -1 isn't!
Always pays to put your solutions back into the original equations to check.
(The other solution is x = 1/2, y = 5)
As follows:
\(\Sigma_{k=1}^6\frac{1}{k}\rightarrow \frac{49}{20} \rightarrow 2.45\)
Not sure if you mean 8x^x is the rate of change, or this is the function whose rate of change is to be determined, so both values are given below:
Enter asin(0.934) in the calculator on the home page here.
Come to think of it, modulus can mean the same as modulo!
It has several meanings in mathematics. When used with complex numbers, for example, it means the absolute value, so the modulus of 3 + 4i, say is sqrt(3^2 + 4^2) (i.e. 5)
x4 + 4x3 – x2 -16x – 12 → (x+1)(x+2)(x+3)(x-2)
Mod() is the modulo function.
