Start on the right side.

Write <math><mstyle displaystyle="true"><mi>tan</mi><mrow><mo>(</mo><mi>a</mi><mo>)</mo></mrow></mstyle></math> in sines and cosines using the quotient identity.

Cancel the common factor of <math><mstyle displaystyle="true"><mi>cos</mi><mrow><mo>(</mo><mi>a</mi><mo>)</mo></mrow></mstyle></math> .

Because the two sides have been shown to be equivalent, the equation is an identity.

Do you know how to Verify the Identity sin(a)=tan(a)*cos(a)? If not, you can write to our math experts in our application. The best solution for your task you can find above on this page.
