Small Angle Approximations
LEARN & MAKE NOTES
A concise video lesson covering everything you need to know as quickly as possible
TEST YOUR UNDERSTANDING
This is what you're aiming for - can you apply your skills to an exam question?
TEMPLATE NOTES
Using the TT Template Notes reduces 'cognitive load' while you're making notes, which helps more of what you're learning to go into your long term memory.
Choose between making most of the notes yourself on a basic page structure (BLANK) or to simply 'fill in the gaps' and annotate a more complete set of notes (ANNOTATE ONLY)
SPECIFICATON POINTS
Small Angle Approximations
Understand and use the small angle approximations for $\mathrm{sine}$: $\sin\theta \approx \theta$
Understand and use the small angle approximation for $\mathrm{cosine}$: $\cos\theta\approx 1-\frac{\theta^2}{2}$
Understand and use the small angle approximation for $\mathrm{tangent}$: $\tan\theta\approx\theta$
