Webb26 mars 2016 · For example, follow the steps to prove this identity: Break up the fraction by writing each term in the numerator over the term in the denominator, separately. The rules of fractions state that when only one term sits in the denominator, you can do this step because each part on top is being divided by the bottom. You now have. might as well doWebbThere are several options a student can use when proving a trigonometric identity.
