Paulister 757 Posted February 1, 2016 Share Posted February 1, 2016 h0i folks. I'm an IB student and I can help with math, physics, chemistry and psychology. (Although, in psychology all I can do is to tell you "READ!") Tell me if anyone needs help! :D Link to comment Share on other sites More sharing options...
Paulister 757 Posted February 2, 2016 Share Posted February 2, 2016 Can someone explain the purpose of parametrics bc they seemed utterly pointless and I don't get why they're referred to as rectangular And how we know where the input the equations given I hope that made sense lol What chapter is this again? Vectors? Functions? Sent by Alan Partridge Link to comment Share on other sites More sharing options...
Paulister 757 Posted February 2, 2016 Share Posted February 2, 2016 Well this is unit 8 or smth on my class It correlates to polar (radians, theta) Oh that's vectors. It's just another way to describe a line. It's actually the most fundamental ways to express lines and probably the simplest way to do so. You just need a point on the line and a direction vector that is parallel to the line. Same goes for planes. In this case you need a point on the plane and two direction vectors, one parallel and one normal to the plane. I don't know about you, but we use these vector equations a lot.

Paulister 757 Posted February 3, 2016 Share Posted February 3, 2016 Is there really a part of a microscope called the 'light focus lense'? Was shakespeare really gay? Link to comment Share on other sites More sharing options...
Paulister 757 Posted February 8, 2016 Share Posted February 8, 2016 I was given volume = 3.53* 10^(-23) cm^3 how would I make it mL/cm^3? Thanks! I'm guessing you want to make the conversion. You don't have to multiply by anything. any amount in mL is equal to the same amount in cm^3 Link to comment Share on other sites More sharing options...
Paulister 757 Posted February 11, 2016 Share Posted February 11, 2016 Determine the frequency of a microwave of 6.0 cm in length.( A microwave is an electromagnetic wave. it travels through through at a speed go 3.0 x 10^8 m/s) What is the period of the microwave in above? (I have a sub, and she is not helping at all...) Use the below equation C=f/L C is the wave speed f is frequency L is wave length Then the equation 1/f To find the period.

Paulister 757 Posted February 15, 2016 Share Posted February 15, 2016 can this thread be also used to ask how one studies for a particular subject? Yes. Depends on what educational system you're on (IB, A levels etc). Link to comment Share on other sites More sharing options...
Paulister 757 Posted February 15, 2016 Share Posted February 15, 2016 i m specifically looking for physics (physical chemistry) and not just the generic answer of trying to do as many questions as possible (as i m doing it already) but maybe something different Is this IB Physics? If not, then I can't help you... In general, however, I can tell you that there are a lot of lovely sites that show many study skills, tips and tricks and whatnot.

Paulister 757 Posted March 27, 2016 Share Posted March 27, 2016 Could anyone help me with my online calculus homework?? The answer is this: Where does the "- (z - 24)" come from? Well your method of finding the tangent is wildly different from how I would solve it... I'll try with my method and see what I can get. 1 Link to comment Share on other sites More sharing options...
Paulister 757 Posted March 28, 2016 Share Posted March 28, 2016 Omg you're a lifesaver, thanks! I've got my answer already, but thanks anyway :lol: We haven't done partial derivatives... I know a whole slew of other calculus stuff, if you need me. [emoji4] Sent by Alan Partridge Link to comment Share on other sites More sharing options...
