Because you have to think which value to choose. Doesn't sound that big a deal, but when dealing with time intervals between two or maybe more points it can get a bit messy. That's when I think the way I proposed would be most useful.
You are correct. But I'm not trying to find traveled distance from time -in fact the opposite (time from distance travelled). The way it usually goes is you get displacement and in order to find time you solve the trig equation and filter out the solutions. But if you use distance traveled as a...
In school we have numerous exercises that ask you to find the time when a body passes a certain point for the nth time in simple harmonic oscillation. But it is a bit mentally taxing to solve with the actual formula of x=Asin(ωt + φ), just because you have to sort out all the infinite solutions...
Well, my thinking was that if we cut a continuous spectum into infinitely many frequencies - and each frequency has its own energy- the infinitely many energies of all frequencies when added up would result in infinity. But this thinking is flawed. As said above - and thanks for the many...
So, if I understand this correctly the finite energy is explained by the fact the sun's spectrum is not originally continuous and gets continuous in the way??
In school we are taught that sunlight contains all different frequencies of light. Also that each frequency has it's own unique wavelength and energy (per photon). So my question is that if there are infinitely many different wavelengths of light (much like infinitely many numbers in an...
Oh right, didn't think of that actually. Well, from the remainder theorem we get 1) V(2)=P(2)=10 2) V(-3)=P(-3)=5 . Then you solve the system for a and b. Thanks!

Polynomial P(x) when divided by (x-2) gives a remainder of 10. Same polynomial when divided by (x+3) gives a remainder of 5. Find the remainder the polynomial gives when divided by (x-2)(x+3).
