Really need help! If sin x = 1/a , a does not equal 0, which statement must be true?
csc x = a
csc x= -1/a
sec x= a
sec x = -1/a

sure i'm up for it

step-by-step explanation:

the domain of a function is the set of input values, x , for which a function is defined. the domain is shown in the left oval in the picture below. the function provides an output value, f(x) , for each member of the domain.

a_n = a_1 + (n - 1)d

the first term is 6.

the common difference d = ?

when you find d, replace n with 7 and d with the common difference to find your answer.
