Very the identity:
sin(A+B)/sin(A-B) = tan(A)+tan(B)/tan(A)-tan(B)

Explain steps :))

Write the converse of the following statement: if the trees have no leaves, then it is fall. if the trees have no leaves, then it is fall. the trees have no leaves, therefore it is fall. it is fall since the trees have no leaves. if it is fall, then the trees have no leaves.

Which of the following is a function? a.) {(-2, -4/5), (-1,-,,-1)} b.) {(-2,,1/,3/,1)} c.) {(-22)} d.) {(-21)}

Consider the sequence below. 3 , 1 , 1/3 , 1/9 , select the explicit function which defines the sequence.
