Question

For which angles (given in radians and degrees) is the percent difference between x and sin(x) less than 1.0%?

		1 degree or 0.0175 radians
		5 degrees or 0.0873 radians
		10 degrees or 0.1745 radians
		15 degrees or 0.2618 radians
		None of these have a percent difference less than 1.0% because the angles have to be really small.

Answer 1

Given:

For which angles (given in radians and degrees) is the percent difference between x and sin(x) less than 1.0%?

		1 degree or 0.0175 radians
		5 degrees or 0.0873 radians
		10 degrees or 0.1745 radians
		15 degrees or 0.2618 radians
		None of these have a percent difference less than 1.0% because the angles have to be really small.    We want ---    . You have to have your calculator in radians mode and use the radian values : Try --- ---    is true . Try --- ---    is true . Try --- ---    is true . try --- ---    is not less than . Of the choices , we then have the percentage difference between and   is less than 1% only for the first three choices : equivalent to   ,   equivalent to   , and equivalent to    ---- SOLUTION .
