Question

If sec A = 3/2 then find tan2 A ( tan 2 means tan square)

Answer 1

Answer:

tan² A = $\frac{5}{4}$

Step-by-step explanation:

Using the identity

tan²x + 1 = sec²x , that is

tan² A = sec² A - 1

           = ($\frac{3}{2}$ )² - 1

           = $\frac{9}{4}$ - 1

           = $\frac{5}{4}$
