Show that the following statement is true by transforming the left side into the right side.
?

What will be an ideal response?

We begin by writing everything on the left side in terms of sin ? and cos ?.

?

?

Since we have succeeded in transforming the left side into the right side, we have shown that the statement  is an identity.
