If given A,B,C, Find constants x,y |xA +yB=C

AI Thread Summary
To solve for constants x and y in the equation xA + yB = C, where A = 2i + 3j, B = 1i + 5j, and C = -1i + 3j, the approach involves separating the vector equation into its i and j components. This results in two distinct equations that can be solved simultaneously. The initial thought of relating the equation to the slope form was deemed unhelpful. The focus should remain on solving the component equations directly. The discussion emphasizes the importance of breaking down the vector equation for clarity in finding the constants.

Homework Statement


Three vectors are given:
A=2i+3j, B=1i+5j, C=-1i+3j
Find constants x and y such that xA+yB=C

Homework Equations


N/A

The Attempt at a Solution


The form of the final equation reminded me if standard form of a slope, so I found the total vector for A,B, and C. I was then going to put it in the form Ax+By=C, but then I realized I’d be solving for slope, and I don’t think that’s the direction I want to go.

try separating the vector equation xA + yB into their two components - that is two equations, one for i and one for j
 

Thread 'Errors and significant figures'

I multiplied the values first without the error limit. Got 19.38. rounded it off to 2 significant figures since the given data has 2 significant figures. So = 19. For error I used the above formula. It comes out about 1.48. Now my question is. Should I write the answer as 19±1.5 (rounding 1.48 to 2 significant figures) OR should I write it as 19±1. So in short, should the error have same number of significant figures as the mean value or should it have the same number of decimal places as...

Thread 'A cylinder connected to a hanging mass'

Thread 'A cylinder connected to a hanging mass'

Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
