1.7.14 Small angle approximations (A-level only)

Card 1 of 20

Which unit must be used in the standard small angle approximations?

A

Since 1−cos⁡x≈x221-\cos x\approx\frac{x^2}{2}1−cosx≈2x2​, lim⁡x→01−cos⁡xx2=12\boxed{\displaystyle \lim_{x\to0}\frac{1-\cos x}{x^2}=\frac12}x→0lim​x21−cosx​=21​​.

B

x2\frac{x}{2}2x​, for x≠0x\ne0x=0.

C

Radians.

D

Both graphs pass through the origin with gradient 1.
