SOLVED PROBLEMS

1. Express in radian measure (i) 54⁰ (ii) 135⁰ (iii) 330⁰
   (iv) - 160⁰ (v) 42⁰ 24' 35"

Solution:

Since 1⁰     =       =    0.017543 rad

2. Express each angle in degree measure : (iv) 4/3 rad.

Solution

3. The sum of two angles is 100⁰ and their difference is  find the angles in radian.

Solution: Let the required angles be x rad. and y rad. respectively.
