Final answer:
a) Sin x = 0: The solutions are x = 0° and x = 180°. b) Cos x = 0: The solutions are x = 90° and x = 270°. c) Tan x = 0: The solution is x = 0°. d) Cot x = 0: The solution is x = 90°.
Step-by-step explanation:
a) Sin x = 0:
- Set the equation equal to zero: sin x = 0
- Find the values of x that make sin x equal to zero. The solutions are x = 0° and x = 180°.
b) Cos x = 0:
- Set the equation equal to zero: cos x = 0
- Find the values of x that make cos x equal to zero. The solutions are x = 90° and x = 270°.
c) Tan x = 0:
- Set the equation equal to zero: tan x = 0
- Find the values of x that make tan x equal to zero. The solution is x = 0°.
d) Cot x = 0:
- Set the equation equal to zero: cot x = 0
- Find the values of x that make cot x equal to zero. The solution is x = 90°.
