1. Convert -340 deg to radians

            Mode: Radian
            Functions: [MATH] => [ANGLE] => [^o]
            Evaluate: -340[^o] => -5.2270 radians

2. Convert 6.2832 radians to degrees

            Mode: Degree
            Functions: [MATH] =>[ANGLE] =>[^r]
            Evaluate: 6.2832 [^r] => 360.0008 degrees

3. Convert 25.8971 degrees to DMS

            Mode: Degree or Radian
            Functions: [MATH]=> [ANGLE]=> [>DMS]
            Evaluate: 25.8971 [>DMS] => 25^o53'49.56"

4. Convert 1.576 radians to DMS

            Mode: Degree
            Functions: : [MATH] =>[ANGLE] =>[^r],[>DMS]
            Evaluate: 1.576 [^r] [>DMS] => 90^o17'53.34"

5. Evaluate tan 30^o

            Mode: Degree
            Function: [TAN]

6. Evaluate cos 3.142

            Mode: Radian
            Function: [COS]
            Evaluate: [COS] 3.142 => -1.0

7. Evaluate sec 6 (no sec function on calculator
    so use sec = 1/cos or write a function to do)

            Mode: Radian
            Functions: [2nd]=>[x^-1], [COS], [ENTER]
            Evaluate: [COS] 6 [ENTER] => 0.96017... [2nd] [x^-1] => 1.04148 .. Radians

            Evaluate 1.04148^r rads Mode:Degree => 59.67 degrees
