GHAZI TO THE RESCUE!!!!!
consider an example of weight increasing with mass...(physics)... we know that weight = mass* gravity ....so here consider gravity as constant mass= x and weight = y ...you 'll have a linear function as y=k*x
this is called as linear variation
still confused :/
one more example is ohm's law...where current (I)is proportional to voltage (V)...(provided that temperature should be constant ) so it is V= I*R where R is constant known as resistance....so V varies linearly with current ..linear variation means equal or proportional increase in one variable for the amount of increase in other
|dw:1346179148379:dw| voltage is proportional to I
very imma fail this discussion
just consider y= x ...the more you increase x the more y increases...moreover linear means arranged or extending over a line...so values of linear equations will vary in a straight line
so how would a real life thing fit into this?
real life thing is a variation of current in a wire....that i have mentioned above...higher the applied voltage (potential difference) higher will be the current ...but if their graph will be plotted it'll be a straight line
ok soo umm the high you turn up voltage the higher the number but it will be linear on a graph how is that?
higher the voltage higher will be the current ..but graph between them will be on straight line...since they are linear
ok im starting to get it i think.. So for my discussion could i use this but put it in my own words? and ill tell you what imma put to make sure its correct.
Your my lifesaver as always. haha
Ghazi is this the equation for it? F(x) = m x + c
yes...it is a linear equation
so with the votage thing which would be the current and the higher voltage?
for the voltage thing it would be just voltage= resistance * current or V=I*R
this work So a real life situation of linear function it a current in a wire. The higher the voltage that is applied the higher the current will be. But if they are plotted on a graph even though they are changing it’ll be a linear line. The equation would look like this voltage= resistance * current.
awesome that's perfect....sorry for responding late
its cool tahnks
