Very well explained. I am reviewing small angle approximations for my course mechanical vibrations and this was a perfect summary to help me remember. Cheers!
Maybe you need a bot to reply to all these "is this part of the course?" comments.
Is this part of the syllabus?
No, this is an extension video to show you another derivation for interest.
Does this derivation prove the approximations when in degrees too?
The derivatives wouldn't be correct as the derivative of sin(theta) is (pi/180)*cos(theta) in degrees
@@TLMaths I see. Didn't realise it was only tru for radians but I understand now. Cheers
dumb question but what actually counts as small? would an exam question tell you to use small angle approximation, or are you expected to use it if theta is within some certain values?
You would be told that the angle is small. This explains further: en.wikipedia.org/wiki/Small-angle_approximation#Error_of_the_approximations
