alright thanks peeps!

Is air resistance dependent on mass? thanks!

i see , thank you for your explanation.

Homework Statement Hi, with regards to the negative zero error , do we read the vernier scale from the left or from the right? In this case, should it be -0.04cm or -0.06cm? Thank you !

that was very insightful, thank you

yes that was sloppy of me :D anyway, is the even root fractional exponent the only case whereby this rule breaks down ?

hello office_shredder, may i know why the indices rule is invalid for negative numbers? i tried for example, (-2^6) and split them up to [-2^(2*3)] = 4^3 and i still yielded 64. where does taking exponents of negative numbers breakdown? thanks!

alright thanks everyone!

oh... do you mean since 1+kx is a straight line, so at the point 0, it is just 1 + kx ? so if i had a curve, would taylor expansion ( approximation? ) make more sense here? that means the first term of the expansion gives me a straight line, the 2nd makes it more curve, the 3rd makes it...

oh, we can just define a as x? does it mean i can define a as -kx or -k also? but i thought a is the point that we evaluate the taylor expansion on? am i right to say if i taylor expand on a point say x =1 for a curve graph. then as my orders of taylor expansion become greater, the...

hi everyone thanks for helping but the taylor expansion was for x-kx or perhaps only -kx was expanded? but anyway it was given as x - kx f'(x) + ... with regards to the above, how did you get that formula? because i only know this f(x) = f(a) + f'(a)(x-a) + 1/2! f''(a)(x-a)2 as the...

i am very confuse how my profs always use taylor expansion in physics which somehow doesn't follow the general equation of f(x) = f(a) + f'(a)(x-a) + 1/2! f''(a)(x-a)2 and so on... like for example, what is the taylor expansion of x - kx where k is small it was given as something like...

wow... amazing...

is this possible?

A/C means option A and C are correct :D
