Question 1152699: Let sin(45°)=0.7071. Enter the angle measure (μ), in degrees for cos(μ)=−0.7071.
any value equivalent to 360n +
, where n is an integer
If cos(μ) = -sin(45°), as it is given in the condition, then there are two possibilities for μ :
a) EITHER μ = 135° + n*360°,
b) OR μ = 225° + n*360°,
where n is any integer number.
Ignore the answer by @josmiceli, since it is partly incomplete and partly irrelevant.
