Answer:
x = 2πn + 1.4202.
x = 2πn - 1.4202.
Step-by-step explanation:
The angle in the first quadrant ( where n < π/ 2)
whose cos is 0.15
= 1.4202 radians
- the other solutions will 2πn +/- this value.
All solutions:
x = 2πn + 1.4202
x = 2πn - 1.4202.
x = 2πn + 1.4202.
x = 2πn - 1.4202.
These two expressions that together describe all answers to the equation.
