Homework Statement
62. In physics, it is important to use mathematical approximations.
(a) Demonstrate that for small angles (<20°)
tan a ~ sin a ~ a = (Pia'/180 degrees)
where a is in radians and a' is in degrees. (b) Use a calculator
to find the largest angle for which tan a may be
approximated by a with an error less than 10.0%.
Homework Equations
The Attempt at a Solution
I'm unsure how I would go about this other than plugging in numbers less that 20 degrees, but I wouldn't know what is within ten percent error.
