Asked by dennyelle
The equation sec x = −0.5 does NOT have a solution because
a. the equation is not well formulated
b. of the negative value on the right side
c. it means that sin x = −2 which is outside the range
d. it means that cos x = −2 which is outside the range

given sec x = -1/2
then cos x = -2, which is not possible, you should know that cosine as well as sine fall between -1 and +1
then cos x = -2, which is not possible, you should know that cosine as well as sine fall between -1 and +1
